OK, make the legal age 25
sorry if this comes off wrong, but.......
would you let your kids smoke pot? or would you let them idolize someone that its public knowledge that does? Which does encourage the behavior. Im sure your teaching them to be Steeler fans, but sounds like you don't care if Steeler players do smoke weed. And if you don't let them toke, nor idolize someone that does, do you discourage them from being Steeler fans (or anyone else that does it)
Most parents who give a shit about their kids aren't going to let their kids smoke pot. Nor will they encourage idolization of someone that does. Now if its your favorite team in question and you have to discourage your own kids from being fans, and everyone else follows suit, in about a generation how big do you think that fanbase will be?
even if you don't have kids, as a cop you can project the hypothetical
