What he is saying is that, generally, given the choice, women will prefer social work to asocial work.

Why is it sexist to suggest that women might prefer different careers from men?

Because suggestion that men and women in general are different is criminally sexist. It's what got us here in the first place.

People(republicans) need to get it through their heads that there are NO differences between men and women, period.

Do you have any evidence for this?

IMO, however, there's a lot more "nerdy" personality types among men who are interested in the traits that the programming career offers, and that's why there's so many more men in the field. It is changing, however (see the "brogrammer" trend in the last decade or two), but that, if anything, is pushing women out of the field even more.
