I would honestly say that anyone linking the goblin behaviour to human behaviour is the racist/prejudice one.
Just stop acknowledging that the stereotype is in any way real. Treat it like a child calling you poopiface(which is their best attempt at hurting you btw).
That is the ONLY way to beat racism. Even then, racists will be around being racist. The difference is that everyone will treat their opinion the same way they treat the child calling them poopiface.
What happens next? The impact of racism is greatly lessened. That is the best case scenario because the only other method involves slavery and reeducation camps. People still murder right?
We all agree that is wrong and look at where that gets us. The people who choose to not agree end up where? Right, slavery and reeducation in a camp.
They aren't, but the vibe of this thread already makes it obvious that argument to that end would be fruitless.
