Hell yeah I'm a mermaid! *bites own arm* Chicken flavor confirmed!
Doc, I don't remember this agreement, but that works for me too.

Expressing it differently is, as lydia said, simply like translating it in another language. Whether you agree or not with the word cishet (and no one is also forcing you to use it, we’re just saying that for now it factually exists), it does describe the identity you agree with for yourself (going back to the definition, you are a woman, so you do identify as the female gender you were assigned at birth, and you are attracted to men, so the opposite gender).
It is in no way arguing with the REALITY of your identity. As such, it’s fundamentally different than giving people the identity you have chosen for them, insinuating you know who they are better than they do.
If it’s still not clear, I can give a comparison.

Your last comment tackles a key point: no one is saying you’re not a straight woman, that’s the whole thing.
You keep using a « them vs me » rhetoric, saying your identity is « taken from you », you use words like « lay siege », « subvert », « submit ». But we’re not on a crusade to pretend you’re not a straight woman. Despite what you stated, we didn’t ignore it. You say you are, we believe you. No one is trying to convince you you’re not a straight woman. You are, good for you.

Now for more constructive points:
I’m not saying that the concept of gender hasn’t existed since the beginning of times ; it has. I’m just saying that it has been theorised fairly recently, and this definition is still evolving. It’s like consciousness : we have all experienced this since we came here, but we still don’t know much about it, and first definitions aren’t set in stone.
The possibility of identifying as man despite being born a woman shows on the contrary that the concept of man and woman is still relevant, and deeper than basic organs, it goes with another set of factors that has been less taken into account. Feeling like a man means there's much more to man than just genitals, at least culturally, but maybe even beyond this. It doesn't negate it like you say but can open an interesting field of discussion that would also tell more about feminity and masculinity in general.

Not gonna argue about aggressivity with someone who said "extra stupidity" in the first comment on this post.
.
If that makes it better, to preserve the original meaning of heterosexuality we can say it’s being attracted to cis of the opposite gender. The concept hasn’t actually changed.
.
Don’t take this as me being snobish, but: Martin Luther King is « I have a dream » man, advocated for Black rights in the 60s. Not Martin Luther, a monk that questioned and rejected the Catholic dogma during the XVIth century.
.
About religion: I used "goy" to show the existence of terms used by a minority to describe others. You took it upon yourself to compare religion to gender by making an absurd parallel, and I rolled with it to say it didn't even work historically.

Does hitting on ppl on fs usually work? Either way, I'm in!

And how is it bad to be a subcategory? We're all a subcategory of everything depending on the parameter we consider. As a woman, I'm a subcategory of human; that doesn't make me a lesser human. It would be opression if we opposed "cis women" to "women", but every woman having an adjective (used when necessary only ofc) puts everyone on the same level of consideration.
Ps: I got it for the synonymous part, my bad. I focused on the first part, i.e. if they were synonymous a new term wouldn't have been needed. The sentence as a whole seems to imply it was coined with malicious intentions by "them", while it appeared in a scientific article written by someone I'm still going to call a cis man specialising in psychoanalysis and sex research.
While I'm on history, the term gender exists since 1955, and has been put back into question for nearly 40 years; that's normal for abstract concept.

How does cishet require for the meaning of heterosexual to change? (especially since it does contain the notion of "het")
And, this is a question about a ton of things in linguistics, why should society adapt to the words and not the other way around? You can say that trans are a minority, yet a sufficient number of people consider this word relevant for it to have become more maintstream, it has a relevance in our society. It has also prompted a lot of thought on gender on several levels.
Yeah and cishet means anyone who isn't lgbtq+, which is exactly why I made this comparison.
Maybe it didn't happen exactly with Muslims, but enter Martin Luther, who considered himself a Christian even though authorities did not. He said their definition was wrong and effectively divided Christianism into Catholicism and Protestantism. The definition of what Christianism means can differ between these two groups, Catholics didn't calm down indeed at first, yet here we are, both are Christians.

Does one of you know why it isn't called eating out for guys? Since technically it's roughly the same principle, it could fit. I didn't find the answer online.

@creativedragonbaby 's comment made me feel very hungry but also very hopeful for the future. And turns out I was right, my tail's awesome, I can zboïng on it like it's a spring!
So doctor, no secondary effects so far, I feel great. A bit warm, but otherwise it's all good.
Next step in my glo-up is the sauna I guess? Unless you chose another cooking technique, or you're going for sushi?

Shit you're right
How did I not see this!!

Oooh so technically we're even partners in crime now <3

Is this a cry for help/mating call?

Pretty sure there's something fishy but... *gets in*

Do you think words that are synonymous are born at the same time like twins? And indeed, the two aren't exactly synonymous because cishet covers men too, my mistake on that one.
Still, some terms exist that define people outside of a community because they're convenient, for instance since I'm not Jewish I'm a goy and while I wouldn't spontaneously use the term it exists and the definition fits me, saying "I'm not a goy I'm an agnostic" would be semantically wrong. I don't use it but I don't attack it.
If a sufficient number of people are deeply offended by this I guess it will change indeed, but I'm really not betting on this.

How did he find out??

...shit I qualify. For science!
Although please use just a bathtub full of salt water if you want to see if marinating has an influence, BC I can't swim and would drown very quickly at sea.

That's a good point I am trying to consider it but even when filled it doesn't approach a normal cone with some melted ice cream held in the squares. However, this shape, with the tasty material, now we can talk.

Indeed, I'm not gonna be against any group of people based on dumb characteristics like this.
My experience does differ, good call: lgbtq+ I know or talk to are all pretty chill, the very vast majority of posts I see are too. As in any groups it's the craziest ones that are the easiest to perceive from the outside, especially since today's society polarizes things superfast, so I get it can be annoying.
So yeah, no one's telling others how to define themselves, those are good terms.
I say sure, friends!

*jumps on you with the string of my cloak to tie you up while you're still on the ground*

Well you're a keeper, I know you won't cheat!

It got better

I'm gonna keep healing myself but it looks like we won, memesgobrrr!
