By calling someone a stupid woman, it implies all women are stupid.
He could have said don't be stupid.
Rubbish...Why should calling her a stupid woman imply all women are stupid..I imagine every Man and Woman alive have done stupid things......I`m sure May considers Corbyn to be a stupid man probably a lot worse if only we knew.
I think those worried about the fact that he probably called her stupid are the stupid ones !!
