Pride is an expression of sexuality. Proving to ourselves that it is okay for the world to see us as we are. Some people’s sexuality is kinky, that’s just the form some people’s sexuality takes. When a kinky person is gay and they want to express their sexuality, it’s going to look kinky.

there's also a long history of these communities existing at pride, even if they may not inherently be queer. bear, leather, and BDSM communities to name a few have been intertwined with pride and the queer community for basically as long as there's been pride!
