Then why not come up with a better word? They say to never attribute malice to something that can be explained by incompetence, but I cannot help but wonder if tying essentially class-based activism against "systemic racism" where class correlates with race based on past non-systemic racism (I base this on reading So You Want To Talk About Race and New Jim Crow and taking copious notes - the former actually says that even if every single person became genuinely non-racist the systemic racism would still not budge, among other things) is a ploy that the movement has evolved semi-intentionally. If you argue for class-focused equality, there are various arguments that could be made against you from morality, history, etc. If you tie it to race, suddenly the counter-arguments seem racist.
