I'm actually not surprised that he got fired, and I do think the firing is justifiable. Writing open manifestos against company policies on controversial and sensitive issues is going to get you in trouble. It just will, whether you're at Google or 'Dave's Grill-house'.

But that's not what I was responding to. OP implied this guy is a racist or a misogynist and stated she couldn't work with someone who held his kinds of beliefs.

I've read the manifesto and it's not as strong as you make it out to be. For example, I've argued that you can't expect perfect proportional demographic representation in a free society in any field. It will not happen, for a variety of reasons that may not be nefarious. If women are under-represented in programming it may not be because of sexism.
