One might argue that the author hasn't done an effective job of welcoming women to coding. One might even argue that the author has misguidedly had the opposite impact than he intended. But claiming that the author is misogynistic seems way overboard to me.

And the fact that people are commenting on the author's agenda could be evidence that people are defensive or in denial that they are part of a system that is biased against women as much as it is evidence that the author maybe hasn't done the best job of combating that problem.

Please apologize for insinuating the author is a mysogynist. I see no other comments that come even close to implying that.

Oh, please. All writing is inherently motivational. Dispassionate writing on the web isn't very inspirational. Write passionately about anything and you'll be bound to piss off some group or constituency. This walking-on-eggshells, I-can't-write-a-line-until-it's-group-vetted stuff kills creativity and makes everything it touches stale.

I do not see how anyone could possibly believe the author is exhibiting misogyny. Perhaps you are confused by the meaning of the word:

Misogyny /mɪˈsɒdʒɪni/ is the hatred or dislike of women or girls.
