Several times, online, I have seen men bemoaning the new stereotype on television, the foolish man. He is bumbling, and doltish and laughable. TV is saying all men are Homer Simpson, or are, at least, a little idiotic in comparison to their more couth and eloquent wives.
It took a while for me to realise what bothered me about this complaint.
And this is it. The stupid person is a stock character, especially in comedy. The drunk, the klutz, the fool. There are gendered and variously aged versions of different types: the bimbo, the naive innocent, the curmudgeon.
There have always been plenty of idiot male characters, the difference is that they were always the butt of jokes and condescension from other men. All that has happened now is that is is acceptable to show a man who is less intelligent in some or all way in comparison with a female like his wife.
This is noticeable only because it was previously simply not allowed.
