And if the level of murder in teachers is no different than in the larger population, then there is a problem with murder in US teachers (as a result of there being a problem with murder in the US).

Even under the grossly unsubstatiated assumption that there is particularly a problem with murder in the US - rather than some specific murderers (or white supremacists, as the case may be) who know perfectly well who they are and will not respond to 'raising awareness' about 'anti-murderism' - presenting that as "Murder by US teachers is in fact a big problem." is at best ridiculous cherry-picking.

Replace "teachers" with "police" and you do get a reasonable argument. In a situation where someone has outsized authority and influence, even a baseline level of <bad thing> is worse than normal. If you're looking to affect outcomes most significantly, reducing "racism" amongst teachers is probably going to be more impactful per $ than reducing it amongst the general population.

Not really. I'm fine with a baseline level murder by police (at least to the extent that I'm fine with where that baseline is in the first place, which is admittedly not a given), provided there is also a baseline level of punishment for said murder. The problems with police tend be either that there is a higher level of murder by police than the general population, or that there is a lower degree of punishment for it.

Also, of course, I don't grant that there is a problem with racism in the general population in the first place, since white supremacists and social justice warriors combined are substatially in the minority. You might be able to make a credible case that racial bias is a (minor but worth addressing) problem, but noone's done so lately, and you'd need to start by making it clear that the thing you're talking about is fundamentally distict from a explicit belief that one race is inherently better or worse/more or less valuable than another, as white supremacists and social justice warriors believe.

We aren't talking about simply a baseline level of murders, but murders due to (or influenced by) racism. Even if you're okay with a baseline level of murders by police, whatever that level is, I hope you'd have problems with a distribution where the victims are solely black people (or to be more real-world, where murders of black people are punished less severely and less often, thus giving greater incentive [or equivalently, less disincentive] to kill people of a certain race).

In such a situation, the same "amount" of racism/discrimination/implicit bias has an outsized impact due to who wields it.

The same applies to teachers. If a random person believes that black people are predisposed to academic failure, that's bad sure, but won't negatively affect many black children. If a teacher who teaches black students holds that belief, that will influence how that teacher teaches those students.

> social justice warriors belive

This is a mischaracterization of what anyone I know who would consider themselves a "social justice warrior" believes, so I think at least some of your objection is due to a misrepresentation of the statements being made by these people.
