I can’t help but think if normal, heterosexual people were inclined to have a parade, just to promote heterosexuality, you wouldn’t see that many, or any naked people in the parade...
Certainly nobody that you would WANT to see naked.
I think you have a great idea there. The time has come to do the obvious. A Heterosexual Pride Parade.
It's time normal people take to the streets in a show of solidarity and numbers.
