That women who don't shave their legs and underarms are gross and unhygienic.
A couple of years ago I discovered that the hygiene argument for shaving was originally aimed at men with beards, and with right. Before modern hygiene standards, many men had overgrown beards with food crumbs and dirt caught in them - truly disgusting. So when razor companies wanted to expand their market, they managed to convince everyone that visible body hair on women is also gross, which coincided timing wise with women first starting to wear short skirts. Somehow today, it's still acceptable for modern men to have beards and their hygiene is never questioned, only their poor sensitive skin from daily shaving or hiding a weak chin, whereas an unshaven woman remains gross.
Despite knowing this intellectually, and accepting that men don't shave their underarms, I haven't (yet) managed to stop shaving my underarms, not even in winter when no-one other than my husband (who doesn't care) would know. I can't stop feeling that it's unhygienic and a trap for sweat.
