I find it hypocritical this nasty term is freely available for use in general society. People get bent out of shape with terms like the n word, racial jokes and sometimes mere mention of race, but the general public seems complicit in slurring white people with this derogatory term. It clearly has racial overtones ("white" is literally built into the term) and it clearly is meant as a slur. According to the nonsense usually attributed with the term "racist" Racism is a nonsense, malicious term (debateart.com) , SJWs and progressive should be calling usage of this term "racist". Yet, these SJW and progressive people are usually the ones calling various white people this racial slur. This is a case of systemic racism against white people.
It's also true that this "white supremacist" racial slur is essentially an attack on white groups in general, whereas other racial groups are allowed to form groups without being slurred. If we search the term "white nationalism" on Wikipedia, we see "Analysts describe white nationalism as overlapping with white supremacism", whereas a search of the term "black nationalism" has Wikipedia making the term free from black supremacism: "Black nationalism is sometimes described as a euphemism for, or a subset of, Black supremacism and Black separatism, and these terms have often been used interchangeably by journalists and academics.[2][3][4] They are in fact very different philosophies". So, despite having white and black people attempting to form ethnostates, only white people are slurred -- more systemic racism against white people.
I think SJW and progressive types need to thoroughly reconsider their usage of this racial slur against white people, because not only is it thoroughly hypocritical, it's indicative of racial hatred against white people.
