> why is it okay for sex fetishists to act out sex fetishes in public around kids?

I don't think that's what furries generally do, nor homosexuals for that part, unless you count holding hands or kissing each other on the mouth as "acting out sex fetishes in public"? I don't think I've seen that even once, but living in a "party city", I've more than once seen drunk heterosexual couples having sex in the streets and in the metro.
