I've witnessed one gay pride parade; how many have you seen? The one I saw was G-rated; I know they haven't always been and maybe they still aren't everywhere, but the fact that you think you can build an argument on a parade reinforces how preoccupied you are by the physical acts associated with sex, especially with gay sex.  
I received notice yesterday of a post from you that I can't find on the board. In the snippet that appeared in the notice, you write that "people get mad" at you when you refer explicitly to sex acts. Maybe some of them do, but I doubt it; mostly I think they are just commenting on your pathetic (a popular word for pathological) preoccupations.
Also missing from the board is a message you posted referring to the sexual orientation of a priest who writes on these topics. I suppose the moderators thought your speculation was inappropriate. Without repeating the name: On what basis did you speculate about his sexual orientation? Why did you think it was relevant?
