It drives me crazy that many poor able bodied white men don't understand that they they can simultaneously have male and white privilege, whilst being very disadvantaged compared to others in society who might be black, gay, female, or disabled.
White privilege is nothing more than saying that as an unemployed white man you have a bit of an advantage over your unemployed black neighbour - it doesn't mean that you are not being screwed.
I think I would argue that class (or rather wealth) is the most important privilege one can have. Obviously I would never wish to be in this position, but I can imagine that a wheelchair-bound black lesbian might find life relatively (compared to many many others in society) straightforward in many ways were she to have £100m in the bank to pay for whatever help and support she needs.
Backtrack - I'd rather be healthy than wealthy and were I sitting on a pot of cash and struggling to breathe I would not feel privileged.
