Thanks for this.
Which systems have you been using lately?
Me?
Oh - 5e D&D (WotC are left-liberal, not SJW) with Paizo material from 2012 and earlier (they were always left-liberal, they only went Full SJW late 2012, around the Obama re-election and associated hysteria). 5e D&D with Dyson Logos (non-SJW OSR publisher) stuff.
4e D&D (WotC, likewise). Mentzer Classic BECM/RC D&D with the old Mystara GAZes and Basic Fantasy adventures.
Recent purchases are mostly OSR - Dan Proctor's Apes Victorious. White Star. Operation: Whitebox.
OK Swords & Wizardry got the old Jesse Jackson shakedown from Stacy "Why does the OSR hate women?" Dellaforno, and have now put out an SJW edition. But I don't think that taints authors using S&W as the chassis for their own games.
I also don't think that WoTC having 100% female artists or typesetters or whatever makes them SJW, even if they boast about it. It's only 'problematic' if they consciously refuse to hire men/whites/straights whatever, and I've seen no evidence of that. I don't believe in 'disparate impact'; there are jobs women like doing more than men, and vice-versa.
I live in London, so most of my players are left-liberals. Obviously they hear a lot of SJW crap and it does influence them (or at least their Facebook posting*), but these are not bad people and I wouldn 't want to avoid playing with them. Even right-wing people say stupid things now and again.
Likewise with games & authors, I think it's really important to distinguish some well-meaning guy, who happens to be a Seattle liberal, from SJWs, Antifa and other such banes on humanity.
*A lot of people are defensively conformist, women especially. I have a female friend who I recall posted a very sensible, insightful post about male/female difference (I think it was re romance) and received a lot of abuse from her SJW 'friends'. Now she only posts left-liberal boilerplate. I have a female work colleague who is pretty darn 'based' in private, but on Facebook is all 'refugees welcome!' So I believe in cutting people some slack. In an age of lies, speaking truth (without anonymity) is an heroic act. And most people are not heroes.
