anarchistic and sex-positive version of National Bolshevism

I'm not familiar enough with Limonov to really know what you're talking about, but I'd say that it is sometimes useful to have a state apparatus to facilitate mass-scale coordinated action, so I'm suspicious of anarchism. I approve of "sex-positivity" in the sense that sex is a natural part of life that the people doing it can and should undertake deliberately for the benefit of future generations; I disapprove of the "sex is pleasurable and that's all I need to know, woohoo!" sense of "sex-positivity".

I consider that the denial of White identity and oppression of White people in the US and Europe is intimately connected to the class struggle.

I think we're pretty much agreed on this point. To me it's pretty clear that the ruling elite despise whites who are culturally low-class and therefore feels no guilt about e.g. opening up a meatpacking plant in some rural white town and staffing it with cultural and racial aliens from elsewhere. There is evidence that managers are aware that racial diversity lowers the chances of workers unionizing. And I think there's a sense that to be one of the "fashionable" high-society crowd, a white persion must basically say that white people are bad.

favor abolishing the police, but for class reasons rather than "systemic racism"

I'm curious to see your reasoning on this. To me it's pretty much a given that some people will need to experience the stick, rather than the carrot, to follow the law. When those people break the law, someone must go pick them out of the general population so that the stick can be applied. Whoever does that basically is the police, regardless of what they are called. I don't think you could pull off a police-free, majority-black polity and keep any kind of advanced civilization.
