What a load of unmitigated nonsense.

The persistent male attitude that women, on average, don't really belong in fields like physics, biology, chemistry, medicine, engineering, mathematics etc, predates affirmative action by millennia--and always with the same pseudoscientific justifications, that women are, for biological reasons, cognitively and psychologically unsuited to work in those fields, and more suited to work in "female" fields, such as taking care of children. In light of that, it appears highly unlikely that skepticism caused by affirmative action would contribute--independently of pre-existing underlying bigotry--to even a tiny portion of the discrimination women face in these fields. It's more likely that the increased presence of women in the workplace has made an increasing number of men--and women!--more aware that women are just as competent as men (or, because the world is what it is, almost as good as most men).

I give you an F, Lewk. It appears you may be biologically unsuited to participating in rational discussions.
