Personally I don't care for the classifications but oh well. I'm a gun owner, support gun rights, favor a more Jeffersonian ideal of government, and oppose abortion. If you had to pigeonhole me in one category "libertarian" comes closest. I have no desire to identify as such, because my politics don't really constitute who or what I am, Vegas. It's a classification asked of me on a bulletin board, nothing more.
I must admit that that was very well said. I agree, and I see the wisdom in your words.
I still believe that labels have a utility, but you are right that they cannot (should not) be used to define a group of people.
