For years now, I have been absolutely convinced that the average IQ in Hollywood is dramatically lower than that in the rest of society. That's not to say that folks with lower than average IQs can't be talented actors or musicians; it's simply to say that, far too often, many (not all) entertainers seem almost supernaturally dense. It's not their politics; it's the things they say (and do) to support their views.
Here's some evidence...
"We are supposed to be liberated in America but if our President had his way, we wouldn't be educated about sex at all. Every woman would have six children and we wouldn't be able to have abortions." - Actress Scarlett Johansson
What an overly simplified view of the abortion debate! It's disrespectful to folks on both sides of the political spectrum who take the abortion issue seriously! How monumentally misinformed!
Thank you, Ms. Johansson, for helping to prove the notion of "dumb Hollywood".
