Words matter.
I think you are mixing up systemic and systematic.
I think that's splitting hairs. It's hard to imagine an organization with systemic racism without some systematic issues.
I don't like personal anecdotes because most people are really bad at self assessment and accountability, and especially weaker sailors and officers. Other than people separating within about 6 months, I have never met a bad sailor or officer who knew or thought that he did a bad job, no matter how much he was counseled.
There are obvious cases of racism that occur (using slurs or making bad jokes), and when those happen they need to be reported to the CMEO, investigated, and stomped out. Perhaps more focus on this similar to sexual assault might get sailors more comfortable with filing formal reports.
But more frequently people use race (and sex) as an explanation of being singled out by their supervisors when it actually is their own poor performance that's the issue. For white people this usually manifests itself as 'the DH/XO/skipper is [insert negative adjectives],' although I've seen plenty of 'black/hispanic SNCO/officer always picks me for the bad deals because I'm white' complaints. It's usually bullshit coming from a bottom 10% performer.
Either way, mass self flogging that white people are racist for being white isn't productive. Splitting hairs over systemic vs systematic isn't productive either. What is productive is a conversation on how we can better catch and hold people accountable, and how do we create a culture where people feel more empowered to report these issues.
