It's been my experience that only libertarians truly want to end prejudice and bigotry. For only libertarians truly want you to be free.
I know plenty of people who want to end prejudice against people whom they identify with. Many conservatives want to end prejudice and bigotry against religious freedom. Many liberals I know hear even a mention of race and will let you know that you must be a racist, especially if you're a conservative.
But what I consistently find is that this defense of various cultures and beliefs only extends as far as the familiar, especially when considering the traditional (and highly flawed) left/right political spectrum.
Because you also find the conservatives who are only concerned about Christian religious freedoms, not the freedoms of other religions. And you find the liberals who look down their nose at those they consider 'uneducated', or worse yet, 'prejudiced' themselves. (No, they don't see the irony.)
Only libertarians think you have the right to believe what you want to believe, and no, we shouldn't try to legislate our beliefs onto others, save that one essential belief, liberty for all. Not for some. Not for those we like. Who we consider Christian enough. Or elite enough. Liberty for everyone, even if your beliefs are distasteful to others.
So, if you have a strong dislike for a culture that isn't your own, if you look down on others because they don't fit your mold, that's fine. But be considerate enough to think twice before you label someone else prejudiced, a racist, or a bigot. Because you probably, in some area of your life, fit into the same mold, whether you'd like to admit it or not.
