What consenting adults do with each other is simply NOYFB. However gay pride events continue to parade sexual behavior in a provocative manner that many would not find acceptable from straight people.
This page addresses Trans Pride which is not really part of that at all: It's not about being "proud" or confrontational, it's about not having to skulk in shame every day of my life for something that affects nobody but myself.
Passing as had we been born the opposite sex is the holy grail for many young tans people, but IMO that would be more like surrendering to societal impositions.
Trans pride is not about shocking people, nor getting them to confront their prejudice. Trans pride is about not having to hide in the closet, ashamed of something that nobody should have to feel shame for. Trans pride is about coming out in the open and looking good as a trans person in her (his) own right. Let people see us for who we are, and not for whom they think we might be.
