The name of this sub is racist or is recreating structural racism
The word “Master Race” is clearly equivalent to terms which were used by Nazis and so are today's far right wing and alt-rights.
There are other communities which created similar narratives, especially from the 4chan side, and I think the origin of “PC Master Race” comes from there.
This reeks of thought policing. If language doesn't contain the "bad words" you can't think about it. I for one will not support a society that strives to become doubleplus good.
