And they choose this path because LGBT folks have been getting bullied, assaulted and murdered for just existing for about as long as civilization has existed. If they don't stand up for themselves nobody else is going to do it for them.

The key word is "trying" - most of them are trying to live their lives largely without bothering anyone - except that "anyone" is composed of a lot of people that can't put up with their existence. Not through any fault of the person, just because of the way they are.

I do get what you're saying. But it's a half step away from deriding them for their very existence, which is disgusting. They are attempting to break the status quo in the same way the civil rights movement did.
