kids are what you make them...my girls are dancers/musicians/ artists and they are also excellent students...my son is only in kindergarten but he is a soccer player/football player/baseball player/wrestler (hence the singlet), figure skater, and he is also an excellent student...and all three of them are very respectful but they also know that they are expected to not eat anyone's shit.
my wife and i teach them, train them and we are actively involved in all of their activities. will all three of them always be good people, all of the time? meh, probably not...kids make mistakes, but you correct them and then you move on. but having rules and boundries and (sometimes lofty) expectations, and communicating those will go a long way toward ensuring that they eventually become good citizens and productive members of society.
