Some geeky types will be tempted, upon founding a startup, to thus not have ANY women in significant roles in the company, and to keep it as guys-only as possible; outsourcing as needed and doing the other legal legwork as required to stay under the headcount (is it >50 people?) to avoid the EEOC.
I'll be more than tempted. To be 100% honest, I have that thought every single time I read any article or blog post about sexism in tech. If programmers with a Y-chromosome are exponentially less likely to either sue us or get us labelled sexist jerks in the press, then that's who we're hiring.
Maybe, shocking as it is, women are reacting to real injustices in these cases that you read about in "any article or blog post about sexism in tech". If your immediate reaction to someone being called out for sexism is to distance yourself from women, have you ever considered that perhaps your attitude is sexist? You're assuming in all scenarios that the man is right and being attacked unfairly, disregarding evidence.
