The Confession of One Who Discriminates

Ah yes, I do it everyday. In my choice of music, television shows, coffee, wine, food and, yes, even in whom I vote for.

If I don't like your politics, I discriminate by voting against you.
If I don't like you personally, for whatever reason, I vote against you.
If I don't like you personally, I do not choose to have you as a friend.
If I don't like you because you're a man, I vote against you.
If I don't like you because you're a woman, I vote against you.
If I don't like you because you're Protestant, Jewish, Catholic, Agnostic, Australian, black, or whatever, rightly or wrongly, IT'S MY RIGHT!

So, is there something wrong with discriminating?
