Telling a bunch of female physicists that they have no place in their profession indicates that he's stupid enough that he deserves what he gets.
How can you tell females for the most part are not good fits in physics? Check out hobbies. Women are almost never found in hobbies dealing with scientific or technical endeavours. Hobbies aren't are a choice, no schools to weed you out, no cliques. But females are still not represented in any capacity. This shows either a lack of interests in them by women or an inability to engage in them. That's pretty much what he said.

Well in fairness, releasing the article in the same week a woman shares the Nobel prize for physics (admitted the 3rd time ever in 100 years - but what the hell - she was graduating from McMaster at the same time I was there) shows unquestionably remarkable timing!
