This SJW policing really sickens me. Brendan Eich, Curtis Yavin, Donglegate, "sexist" t-shirt astrophysicist, RMS, now this guy and who knows how many less prominent ones. And the problem is that it's so widespread. I don't know of any community which isn't infected by it.
And really, what can you do about it? If you are not already set for life you can't afford to step out against it unless you are willing to risk your livelihood.
