I've always thought the word preference to be a relatively mild way of expressing one's likes and dislikes. Something that people see others doing, maybe wouldn't do it themselves but could really care less about the fact that others do it if no-one's getting hurt - kind of a celebration of diversity if you like. But in recent debates on here the things that do not conform to people's preference seem to get a rather stronger reaction than that. "Gross", "horrible", a visceral reaction that literally turns people's stomachs and in some is almost verging almost on phobic toward the thing that isn't your "preference". The recent case in point is something as (to me) innocuous as body hair on women, but this isn't to start that debate over yet again (yawn), as it could equally apply to your reaction to others' sexual preferences or a range of other human behaviours. The people called out on such strong reactions tend to get quite angry when questioned about the strength of the opinion expressed too. Does such a strong reaction really come into the bracket of "preference" or is there something a bit deeper going on than that?
