I hear what you're saying, but I'm not sure I buy the argument. Jack Black is not just School of Rock, he's half of Tenacious D. The band that made a movie about cock pushups and wrote "Fuck Her Gently."
Being the goofy dad in Full House didn't stop Bob Saget from being a very blue stand up comedian.
I appreciate you taking the time to respond and express your views, especially knowing what the response would probably be. Diversity of opinion is always important.
