Yeah, that's fair enough. I get the feeling the words themselves might be to broad or vague to dive this far in to them anyway.

"you most likely met many introverts you never even realized were introverts."
I'm talking about people I know who fit the definition to a tee, how do you normally identify introverts and extroverts?
"Personally, I find many of the qualities of an extrovert annoying but I can also realize how they could be positive."
Same.
"So maybe spend some time listening to others opinions on the subject and try to keep an open mind."
Haha, I'm doing that right now.

I think the qualities that make an extrovert are generally positive while the qualities that make an introvert tend to be negative. This is from experience, not strictly definitional. For example, in my experience introverts don't have a tendency to think more deeply than extroverts, they just tend to share their thoughts less. As another example, very few extroverts I've known have had great issue with being alone or doing things alone, while almost all of the introverts I've known have had some form of social anxiety.

Why does it mean that?

I don't think the differences are quite that binary, those sound like things that plenty of extroverted people have.

What are the pros of introversion?

Not a big fan of gender neutral bathrooms, but having a "toilet room" and a "urinal room" seems like the best solution if we're going that way anyway.

This always seems more semantic than ideological though.
Sexual orientation is what you're sexually attracted to isn't it?

But he's not even a pedophile (probably), just a guy espousing an idea.
