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.
Well then let’s just not talk about discrimination. Easy fix
We live in a so called attention economy. That makes your rather negligent overuse of the term “discrimination” a problem because it shifts attention to situations where it’s easy to argue that discrimination is negligible or doesn’t exist at all. That in turn means people are less likely to have any attention left to inform themselves about cases with actual discrimination.
Basically, comments like yours are what I’d make if I wanted to stifle progress and foster structural racism. Heck, maybe you actually are a bad faith actor.
