I don't really care whether I'm flying with a female, ethnic minority or whatever other non-WASP one can think of.
What matters is:
a) Can they do the job and be reasonably agreeable on the flight deck?
b) Do they go out for a beer afterwards? (secondary consideration subject to their personal wishes, of course) Had one lass regale me with her gyno probs

as I fervently wished for CC female or gay male to field the Ahhh sympathy bit
