The Demons of Doom Eternal are referred to as "Mortally Challenged". Its a silly joke in the game. A few Liberals are upset about this and they claim that the game equates Demons with Immigrants. Which is not true.

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life

How Demons in the Doom series are referred to by humans, especially ARC Employees. It’s an ongoing joke showing humans being sensitive to demons that are literally destroying their world. It takes the piss out of recent conversations about “political correctness” and makes it into a joke.
