You can go to a gay pride parade regardless of your sexual orientation. It is about supporting gay pride and the gay community, you dont have to be gay to attend or particiapte.
There is nothing wrong with you going to a gay pride parade. It is for everyone.

You can go to a gay pride parade if you're straight...all it means is that you accept it and support it.
