That one was a bit surprising to me too. I took it as sort of an “equal time” thread to the equally misguided thread somebody else has going about “white culture”. Which I note he has not posted to.
Between him being Irish or English (I forget which), having a messed up relationship w a Filipino or Viet Namese woman (I forget which), having overtly racist parents shunning them both, being sorta socially challenged, etc., he’s got a lot of unhealthy baggage in this department.
Which might explain, but does not excuse, his decision to start the thread, and his ongoing tone in it.
