I don't think banning racism is censorship Loyce, it's just promoting the survival and well being of the human species

.
But it
is censorship. Racial supremacy (whatever the race) is an idea, and if someone can't express that idea because someone is prohibiting people from speaking about it....well, what would you call that if not censorship? LoyceV is correct. If free speech is to be protected, it's generally the offensive ideas that need the defense, not inoffensive speech that most people agree with.
interesting side point, I have no objections against free speech, it's meaningful to talk about whether certain races exhibit superiority or some other generalized patterns in some areas.
But using this line of thinking to then create unfair and provably false disadvantages to certain groups, with no regards whatsoever to ethics or due process; this I believe would be a bannable offense in any community or organization.
It's also philosophically incorrect as it would imply reverse causality. The proponents of the racial theories often overlook that while an
average statistic about the distribution of a certain race's IQ for example might hold some merit, the fact remains that individual outliers from any race or nationality can still manage to (and do) outshine everyone else.
That is the power of individual genius,
and what philosophers like Hegel would call a momentous, world-historical individual, carrying the human Geist and existence to greater and more beautiful levels of advancement.
