OK - let's look at it another way. How many of you (Harpsi, Catissleepy etc) shave your legs and under your arms? Something like 90% of women in the UK do, and if you ask them why, they'll say one of 2 things:
"I do it for me because I like the way it makes me feel more feminine or because it makes me feel cleaner etc"
or
"I do it because society / men expect me to".
Do people judge other people based on their hairy armpits? Ummm - actually, yes, they do. Look at Julia Roberts not shaving her pits before that red carpet event a couple of years back - that made front page news!
If you asked everyone on here, honestly, if you saw a woman with hairy legs and a weave coming out from under her arms "does that give you an impression of her, without hearing her say anything or see her do anything", most would be hard pressed not to have at least thought something about it, if not necessarily in a negative way (i.e. European / hippy) etc.
So is it really a big stretch to go from underarms to pubic hair on your fanny? Both are secondary sexual characteristics, both represent sexual maturity and so on. But with one we are quite happy to shave off on a daily basis to make us smooth and "feminine" but when I do the same to my fanjo and dare to suggest it's for the same reasons (to appear attractive to me, more attractive to men and because not doing so seems a bit disorganised or not making an effort IMHO), we all get up in arms about it!
