Look at any LQBTQ+ heavy community and you will see this kind of stuff. I really have no issue with the lifestyle expect it’s become full of shitty human beings. And of course you aren’t allowed to be critical of them in any way or you will be labeled bigot. So all of their social immunities and coddling they currently enjoy has resulted in a bunch of amoral, shithead human beings free to do whatever they want.
I guess I should have said that conceptually I don’t really care if two adults suck each other off, as long as they leave the rest of us out of it. But the reality is that they are overt in all of their behavior and demand tolerance, so you are correct; I do take issue with this behavior.
