this is based on the sheer number of people i know who claim to HATE country music. i'll admit, i thought i hated country music, until i started listening to it.
i have no issue with people stating preferences or anti-preferences. i'm not a fan of techno or anything in the "heartwarming" category of tv/movie. but i don't blanket state that i hate everything in that genre. for every raunchy comedy or adventure movie i do like is 2-3 that i think are stupid.
i believe more in assessing everything on it's own merits. that's not to say i don't have preferences or presuppositions, i just try not to genrecide.
