Language doesn't create problems. Ideas do. Hammer is not the problem: a bent nail is.
So, ideas aren't problematic until someone tries to use language to work them? do not invoke godwins law do not invoke godwins law Okay. Treating someone differently because of their genes - skin color, height, hair color - is detestable: not only are you treating someone based off nothing (one's physical attributes do nothing to describe one as a person), you're more often than not mistreating them (giving one unfair advantage because you like their hair color is the same thing, just positive rather than negative). You may use language to express, describe, admit to or despise such behavior, but the behavior itself doesn't have to involve language: you could treat someone differently without so much as a whisper.
