It's insane to try and compare UIL to private on class or character/respect. I have played both, and continue to add private schools to my schedule. I can say, without a doubt, the type of school you're coming from has had very little to do with the product on the field. Character and class is a learned behavior, which typically begins at home, and builds at the school. I have seen private schools, and public schools, have bad days, and look terrible in spectators eyes. I've personally had opponents talk about a player of mine, and say he has a terrible attitude, or has no class. And yet every other opposing school and coach has raved about the kids character. It's all upon perception, and is very subjective. Kids are allowed to have bad days, doesn't mean they're bad people. But make no mistake, those bad days are equal among teenage boys; I don't care what school they're at. Also, I've seen parents get irate in the stands, because the kids celebrate after a touchdown, or a huge defensive stand. As long as they're not taunting, get off the high horse, and let the kids enjoy the game. It doesn't last forever!
