How about you stop being the creepy old guy at all ages raves and only go to the 19+ ones?
I agree totally.
Its not like kids should be forbidden from partying just because the old people feel like pervs. If you want to be around adults only, go to parties that are for adults only.....dont complain about people of all ages showing up to an all ages event.
I go to outdoors festivals.....Mutant Fest (Goths/punks in the woods) , Rainbow (hippie) gathering, Burning Man, Moontribe back in the day....we had people of all ages, sometimes people brought their kids, and it was fine. Really, it was fine.
Then again, I dont really like these commercial "raves" that much either.....I was from the desert rave community, and while accusations of elitism might be fair, we tended to look down our noses at really commercial club parties unless they were underground werhouse parties for small donation....regardless of the age group, the quality of the attendees tends to be different and at the outdoor parties and festivals that last days you actually have a sense of community....campfires, tents.....nothing like having a tent at a party for when you meet somebody you like

. Sure beats pissing hundreds of people off when you blockade the restrooms.
At some of these ongoing festivals you see people who are under 10 years old and also people who are over 60. We have an awesome time, better than most people just partying in a club for 6 hours.
