I defined the terms you asked for, iirc more than once. I did it by looking in the dictionary.
Arabella is completely right here. We've explained over and over and over again that it's inappropriate * to use bystanders, including chidlren, as props ina paraphilia based, sexually gratifying act.
You've responded with:
you're obsessed with policing sexual behaviour (and behaviours that you regard as sexual) aren't you, and screaming "paraphilia" at anything that lies outside your own world.
We've said that we're not policing it, or suggesting others do so. The point is what is appropriate around children, not what is legal. We are not "screaming" (hysterical, pearl clutching...) anything, we are calling a recognised sexual disposition by its name. Reputable source upthread.
This isn't even controversial!! If you ASKED them what they're doing, they would most likely explain that it's a sexual thing. The reason why 'kink at pride' is something that people dressed like those boys defend is because these things ARE kink. I've already defined kink for you, so don't even start asking me what I mean by that.
*not illegal, not illegal to think about.
