Nah, real reason SJWs prefer not to make their own games is because they're lazy, entitled and inept. They're so devoid of any genuine values or principles, and can potentially make so much money from Kickstarter, even if they don't fullfil their crap, that they'd jump at the chance to grab that cash if they were willing to actually DO something, instead of just whine that somebody else hasn't, which is far more effortless and cathartic.
But those who can't, teach. And those who can't teach, criticize. And SJWs can't even criticize well, cuz they lack the internal logic or consistency to even do THAT. So they just whine instead. And on the off chance do something, it's products like these, where you can't even tell what they offer that's different from other RPGs.
