This thread moves too fast for me but i got enough of the old, old, so-fucking-OLD "kink at pride" debate to learn kiwifarm was full of prudes. Weird.
I am not a big fan of men in leather thongs walking on all four but i don't think it's worth clutching my pearls. Sure kids might sense that it's transgressive and maybe even be a little uneasy, but a lot of things will do that to them in public spaces. You can't have a city without the occasional crackhead or guy pissing in the street. It's up to the parents to be there to sooth them, and provide an explanation/context to the things they might see. They will see way worse things than that if you let them get unsupervised access to the internet. Or even if just their friends get that unsupervised access.
I think Prides are, in some way, a continuation of old Carnavals and Feast-of-fools type of celebrations (you even see people being walked around by their dogs in the Hunchback Disney movie, now that i think about it). It's a party, an overflow valve where normal rules don't apply. Societies rules are being turn upside down for a short moment. Humans needs those valves to function, and i envison this very forum as another kind of valve where society's rules don't apply, at least that's why i went here. So i can be transgressive in a way i can't be almost anywhere else.
Which is why it's different to be half-naked at prides/ in leather at prides, and doing those things at a normal restaurant, in the subway or the street at any other day. Pride is an acceptable context to showcase your kink (to a degree) but a normal context isn't.
But i am not taking my kids at Prides, because Prides are not fun to me.
