Why our LGBT community act like this .....?

I know we are constantly fighting for our rights, but do we have to act like basically "s" i mean in gay pride some guys really take it over the top basically naked and acting promiscuous, im not saying that we should be saints, but that is just........., if we want to win the fight against haters we should not portray the wrong stereotypes, but if we dont act like we do, then we would basically be boring str8 people..... idk its a complex dilema what do you think?
