The point is them both interact with your kids and one of them is showed as badass and cool. Who would a kid listen to?

There is no double standard here. One is an entertainer. One is a teacher. They aren't held to the same standards.

Yes, they don't have the same weight so it's ok... at least it was ok 'till some time ago but now internet is teaching kids that something is cool and correct if it has many likes (that's why most youtubers do the same things)... what usually gets many likes in internet? the dumbest things around. As far as my experience goes, kids are getting smarter but they are making less personal experiences, they learn from youtube mostly...and well that's not so good if they can't filter by themselves what is useful and what is crap, as grown-ups they are gonna do what they learnt and I highly doubt a good teacher would be able to counter the effects of years of whatever new lows they get to see.

Well, it sure isn't going to get any easier, that's for sure. Which subject are you going to be teaching, BTW?
