Racism is about more than being race-conscious. I think we all recognize that. I can say 'Obama is black' and 'John Boehner is white' and 'How many Asian senators are there?' None of these questions subjugates anyone.
For systemic oppression (and Racism), there has to be a group in power and a set of institutions created by those in power to subjugate others.
Back to the point: speakers often speak about Racism (which, as above, requires the power to create oppressive institutions) in the same way they speak about what you described as 'opposition to the majority establishment and a black counter-culture that opposed race equality and integration.' This probably happens because the nuanced description you gave doesn't roll of the tongue.
My ultimate point: it's not clear to me that an ethnic group that is not part of the 'majority establishment' can be 'Racist'.
