Perhaps I can give you the benefit of the doubt here. But that is definitely what it sounded like.

well gosh, most of us were pretty aware and discussing the concept by HS. It's not at all controversial in liberal circles. Never was. Sorry to disappoint you.

If that's really true, it honestly sounds like that you're not that much older than I am, or you went to a super-liberal school, or both. For full disclosure, I did attend school in the suburban D/FW area, so maybe that might help explain it a little, but you'd think that at least some members of the general public would have a better understanding if "white privilege" actually was taught or even discussed in many high schools.....but this doesn't seem to have been the case, apart from perhaps a few rare exceptions.
