To be honest, you can replace "left-winger" with "right-winger", and the second caption would still hold true. Plenty of people on both sides are guilty of refusing to discuss solutions. It ends up being an "It's all about *ME*" mindest.
Granted, but the argument itself is about leftists hating to be called "NPCs", they claim it dehumanizes them, despite the abundance of dehumanizing language they use. Yes there are people on the right who are just as bad, but at the moment right-wingers don't have much sociopolitical power or public opinion backing them/
In other words, a leftist getting angry about being called an NPC is like a white man getting angry about being called "whitey" by a black man.
