In a grand scheme of things, creation of memes outweights racism. Good memes are eternal bits of cultural heritage. They provide conceptual ground which can be relevant thousands years in the future. Slurs, racism and neo-nazis are temporal problems of modern times. They will be solved and forgotten about, but memes aren’t going to die. We don’t care about horrors of trojan war, but Trojan Horse is a useful idea for humanity. Such ideas aren’t born from taboos or censorship. There is some value on setting that is productive to them, even if it is a tragic and miserable place full of negativity and dark sides of the humanity.
