im in my early 50's, i know guys as old and older then me, that are the dweebiest players around. they pick, they HO, then they scream about ethics, and how the game has degenerated, but only when they get beat. i try to lead by example. sure i ho on occasion, i pick on occasion too. but i don't scream or yell when it happens to me, i just up a new plane and start over.
i think blaming the younger crowd is a way of excusing that particular persons behavior. there are bad players of all ages, as fugitive said. picking on the young players is just a way of justifying that they, themselves, are crappy players.
