True, but it's a bit of a slippery slope, dealing with people that are 'proud' of something like that. People that buy heavily into a sexual culture like that are just like people that are into weed culture, [insert race] culture, or even heavily into a religion--mostly in the fact that, if you don't also feel strongly about the subject they do, it can be hard to get along with them. I've associated with people that shout their pansexuality to the heavens, people that are hyper-religious and rattle off quotes from the Bible, people that smoke weed every day and wear clothes with pot leaves on it, and they're all practically the same in terms of mentality. Many people are just about that one thing they base their lives on, and nothing else, and people that aren't about that one "culture" (or even people that are into said culture, but not THAT much into it). It's less like that's a part of them, and more that that IS them. This sounds mean, but they typically aren't a person that "enjoys video games, goes to a biking club once a week, and happens to be a bisexual", but rather is "I'm the ___sexual". They're trying to fill a hole in their personalities with a culture because they are failing to make themselves into a unique individual, for whatever reason.
So, yeah, I sorta agree more with Rest with what he said.
