Looks like carpet bombing to me

That's valid, but I do think it's a generalization. Religions do converge quite often. In fact I'd even say that it's inevitable that they do come together, since they're mostly pursuing the same goals.
Science comes together because of how it's been defined. The method was created in such a way that everyone (ideally) wluld agree. Religion (as a whole) doesn't do that. Many would even say that the diversity of perspectives on that religious tree is perhaps its greatest strength

That's hardly a fair comparison; the vast majority of the wars you're referring to occurred before science was even really a thing. And as I said, those wars were just political. Religion was just a weapon. 9 times out of 10 I'd bet the war still would have happened if there was no religion to speak of

Goes both ways. There are plenty of examples of religion bringing people together -- even people of different faiths.
There are even examples of "sciences" causing division.
Basically, division is caused by selfishness and political pressure, nothing more. Neither religion nor science is powerful or compelling enough to trump mankind's desire to be top dog.

@bassinyoface: but never just for the sake of change. The only time something should need to be changed is if we've come across new information that tells us that change would be beneficial. Otherwise we're just doing experiments that are at least as likely to make us worse off than better.

Or stop me from deciding who I want to serve in my restaurant

Oh. I know Xhosa has the same word, ingonyama.

Don't worry, I get the joke. I just think it's funny that making it into a joke is apparently the only way to defeat the argument.

Doesn't matter; nobody's going to look at anything else you're wearing

But how much harder? How many of these people are using guns that they don't legally own to begin with? They're already getting them illegally. So how is making them illegal going to change it?
