I definitely believe it's the lack of corporal punishment and over-emphasis on tolerance and sympathy that is killing our kids. I don't mean tolerance like Gay, ethnic, or shit like that. I mean the vapid Politically Correct tolerance, like if a kid is busy lighting cats on fire, teachersa and parents will say "Oh, he's just acting out." instead of dealing with the problem by punishment or teaching. We have gotten into the habit of non-confrontation in everything, and kids don't learn that way. Also, have you noticed school is getting dumber? I know kids in the U of U that can't do long division, or are in Algebra 101 - you know, the stuff you were supposed to learn in 6th grade?
Reading is thrown out the window in English Classes, Math is dumbed down to accomodate those not good with numbers, Hell, my Science classes didn't even have labs, and PE now includes Dance Dance REvolution and they threw out the mile!!!! NO JOKE!!! Everywhere else in the world, England, China, Saudi Arabia, kids are getting an Education. In America, we get a mandatory Baby Sitting. There's a reason why we're being overtaken as a society, a culture, and a world power by everyone else in the world.
As for kids swearing, I swore some as a kid. I wouldn't say every other word, but def. a little. It's a rite of passage for kids because it's a taboo. Parents don't want you to do it, so you rebel. It's just human nature. If they're still doing it in a couple of years, then you should be worried. Otherwise, just be better than them, and they'll catch on to your attitude and ability. The way to get them to stop is not to kick their asses, but show them that it's just not what the best people do.
