I've also had a boss in tech that refused to hire women engineers. And another boss that lied to the state department to get someone here on asylum (who coincidentally was the hardest worker I've met) sent back, because "Mexicans should go back to where they came from". Spoiler, the guy wasn't even Mexican, just brown.
Oh please. For decades, in the US, there have been programs designed to attract women and minorities to engineering and tech careers. I am of the opinion* that in 2018, women or minorities who are are not in tech, are not in tech because of choices they freely made. Any remnants of discrimination are negligible compared to the advantages that have been heaped upon them.
*I'm sure many disagree with the opinion expressed above, and that's OK. I'm sure many also agree with it. But I would bet that holy hell would break loose if I were to express that opinion in a discussion forum of a FOSS project that has been co-opted by the SJW scolds. And your opinion, which I was responding to, would be permitted.
What I am well and truly fed up with is the implication that it is pernicious behavior on the part of white males that is responsible for this state of affairs. And that's not necessarily relevant to this particular SJW dustup, but in general it is what's implied, when it's not stated explicitly (as it often is).
