Evidence of an employment ratio difference, or even a wage gap (without careful controlling of as many variables as possible), is not necessarily evidence of sexism.<p>Yeah it is. Hear hooves, think horses, don&#x27;t try too hard to eliminate zebras.<p>EDIT: I am one the many reasons women don&#x27;t like working (in tech). Friends of mine are at work, overly enthusiastic when engaging with female colleagues - nothing overt, nothing offensive, but <i>noticeable</i>. 
Smarmy perhaps. It&#x27;s something most women at work seem to accept as normal if distasteful.  I am reasonably certain I am on the smary spectrum.  Problem is I don&#x27;t tell my friends, so they don&#x27;t tell me.<p>And the fact that it has taken me till my forties to have sufficent self- knowledge indicates the world is full of guys like me - and that&#x27;s not a world I want my daughters  to work in.<p>Edit2: perhaps a simpler approach - I get fed up watching people demand incontrovertible proof that they are part of the problem.  If there are climate change deniers, there are sexism-is-a-problem deniers.<p>(Yes of course the two problems are not of same magnitude, but the psychological issues at play are the same)
