A little sample of some of the comments here...
"This is nothing else than the dictatorship of pro-female and anti-male discrimination"
"Most of these complaints lead to dumbing down of conferences."
"It is because of her gender. It might also be because of her content, but it will definitely be because of her gender."
"the vast majority of coders is male (and always will be)"
"There are certain physiological facts (i.e. related to testosterone) you can't ignore or explain with "society"."
"Basically some people are more naturally suited to being coders than others ... And that's why there will likely always be more male programmers than female."
I CAN'T POSSIBLY THINK why women might be put off this industry, it SIMPLY MUST be because of biology or largely discredited theories of personality...!
