Not really an issue, but some people are less attracted to members of certain races. I, for one, find less Asian women attractive than non-Asian ones, for one. The same goes for most black women, while black guys do really well (I usually don't tell them that though, mostly because half the black guys I know personally have huge egos).
On the subject of Sandra not being hot due to being a redhead/ginger: there is a difference between redheads and gingers, yanno?
