My first love was a redhead.....I still remember his hair (down to his waist) falling over my breasts as we....well, TMI.
he was certainly oddish in his own way, but a darling and a worthy and wonderful citizen of the human race.
But really ginger (as opposed to auburn) haired WOMEN scare me a little.
This is because they appear more likely than average to have borderline personality disorders...which, oddly enough, appears to make some actual scientific sense.
I was looking at some data on male vs female pain thresholds...and redheads appear actually to have lower pain thresholds, on average, than the rest of us...eg they need more anaesthetic during surgery.
Given that it appears fairly likely that hyper-sensitivity can be inborn trait that renders us more likely to suffer ongoing damage under the emotional conditions that appear to create borderlines, redheads may really make up more than the statistical share of borderlines than you would expect!
