I've read those kind of threads on many different boards. In my opinion poor parenting can take place anywhere in the world. Most of the people who complain about kids are selfish individuals who don't want their "buzz" ruined. This scene is a family, and my kids are part of mine. I love taking them to shows and seeing all the love and great vibes out there. I love seeing other parents with their kids. A child smiling is on par with a scarlet-fire to me.
