First, before discussing the accusation...
Could we look at social justice? IMHO the idea of social justice -- of a just society where people are treated as equals (an egalitarian society) and respected as equals -- is a good thing that should be striving for. No one wishes to be disrespected. No one wishes to be 3/4 of a human... or less. With that said...
... the problem with adding "warrior" to the idea of social justice is that a conflict is created -- a war. And in the unfortunate psychology of war, there is a side that's "right" and a side that's "wrong." So, instead of working toward change and a more fair, just, and equitable society, the social justice warrior fights a war to re-make society. And in a perfect recent example of the problem inherent in that thinking is... (I know this will sound corny to some)... Dany's fate in A Game of Thrones. Many Social Justice Warriors have become the very thing they fought against -- anger, division, intolerance, censorship, and pseudo-fascism. But, many social justice warriors are also young and do not see this horrible irony.
I am an artist, and while I certainly want an egalitarian society (and have marched for rights of the marginalized), I also believe 100% in a free society where tolerance of others' points of view is essential and respect of others is a close second. And the far Right doesn't get a pass here either. The fact that they are currently arguing for free speech doesn't let them off the hook for their part in creating this backlash through staunch ways that quite often defy logic (every action creates an equal and opposite reaction).
So, while the term "SJW" might be convenient to throw around, I hope that people will think for a moment about the deeper issue... and see that everyone needs to work toward respect, tolerance, and the middle. I certainly don't agree with everything I hear, but I tolerate it -- unless it is advocating violence againrt another.
So, is GoG being SJW or using SJW politics in their business dealings? It's possible. Although I think SJW politics is ultimately going to lose to openness and the middle, I see many video game companies not only bending to SJW criticisms but actively courting SJW players. If GoG had veered SJW, it wouldn't surprise me. But, over time the restrictive straightjacket of SJW politics is going to tighten and strangle game companies -- a few simple changes to accommodate SJW's will over time probably turn to outright draconian censorship. And seeing that true SJW's don't tend to buy many games, I see it as a problem now but not a problem down the road.
Lastly, I hope that those who feel diversity is always bad will accept change... and that both sides can accept that there's room for "toxic masculine" Conan (which is great BTW!) as much as FemShep. There's room for all of it -- just like a newstand where there are magazines for every taste... and no demand that every magazine be for every taste. Please don't make gaming reductive.
Sorry for the long post. Hoe it made sense.
