 ignorant, hiding his power level, or if he’s just so addicted to playing Devil’s Advocate

 Stepping back, as a comment on the phenomena rather than an individual - I don't think that it matters, no more so than their style matters.  

The arguments may not reflect reality, the arguer may be incompetent, but they are consistently and specifically presenting a worldview in which people are devalued and disenfranchised for their whiteness.  

Ironically, I suspect that our tendency to call them ignorant or assume that they're edgelords is a way to avoid the uncomfortable reality of what they keep insisting to be true of themselves, and keep insisting that everyone else is lying about.  Some of them might lean on those euphemizing fictions themselves.  In their minds, they're simultaneously not racist -and- we all secretly agree with these racist things they've been arguing.  Roll that around for a minute and you might start to wonder just what any of us would have to do before they believed that racism was involved - aside from disenfranchising and shaming and genociding the whites, obviously.

I think that's a bit of the fallacy of the beard. We all have implicit bias that we don't sense in ourselves, but few would call that racism, although technically it is. Racism as a term is typically reserved for those whose attitudes about race are significantly out of step with the idea that the races are fundamentally equal. We all have our knee-jerk biases, it only becomes an issue when it becomes substantial and significantly deviates from the norm. Though I would agree that it's a hard thing to recognize in one's self. Most of us are poor observers of our own behavior. Like privilege, racism is largely invisible to those who are racist. Our general lack of insight as people makes for a huge market for psychotherapeutic services. What role the idea of white persecution, that whites are really the oppressed race, is not something I'm all that sure about. You seem to want to put an awful lot of eggs in that basket.
