Imagine that the Ku Klux Klan spent decades co-opting universities, and taught everyone that by nature of their genetics, black homosexual people are evil colonizers.

The students then became elementary teachers so they could brainwash young children with anti-black, anti-gay toddler books; they took over the HR departments, and enacted policies to deliberately hire as many straight white men as possible; they took over media companies, and made sure every film normalized the KKK worldview; they took over the government, and even the military, calling people who complained about the KKK "domestic terrorists".

When you in turn complain about a video game's heroic characters all being Aryan master race blue-eyed "Mary Sue" white males, who run around and slaughter all of the villains and enemies, who all just happen to be black lesbians, I reply to you on Twitter: "What, you don't like having white people in video games? What a snowflake!"

I think most Leftists today who make that kind of argument are feigning ignorance: they are merely trolling with the strawman. But for those among them who legitimately don't get it, well... try exhibiting some empathy using the above mental exercise for practice. And if you still don't get how ridiculous your position is, watch this video.
