I appreciate your measured response, Marah.
This is one of a few "hot-button" issues for me (and I'm feeling a little, uh, hormonal, today, too, it seems).
I love being a redhead, but it is so horrible having total strangers --- or friends, even --- comment on the alleged color of one's pubic hair.......or just to have people constantly remark, for good or for ill, on one's appearance. There are nicknames, and insults, and possibly the most horrible of all: the obsessives.
So, while I understand you weren't trying to excuse why it happens, it's my feeling that there are a hundred, or a thousand, reasons, and none of them are very comfortable (for me at least).
