First off:
Being closed minded is NOT necessarily a bad thing.
As an example, I am closed minded to the subject of having sex with any woman who is not my wife.
I am close minded to the subject of doing heroin.
I am close minded to the subject of taking a pottery course.
Granted there are some subjects where being a bit open minded is probably for the best, but to make a blanket statement that being closed minded is always a bad thing is just wrong.
Second: As some other posters have already demonstrated very few people agree with there party 100% of the time.
I consider myself a conservative.
But I feel VERY strongly for gay rights. You won't find a bigger supporter then me.
I believe that there are things that are against the grain of conservatism that are necessary evils in our society - like minimum wage. On a perfect planet in a perfect universe I agree that minimum wage is not needed. But we don't live on such a planet. The country we live in minimum wage is here to stay. Since it is here, we might as well deal with it accordingly.
Illegal immigration. While I do believe that the key word is 'illegal', I believe that something in the middle is far more appropriate.
But at the end of the day if you were to give me a questionnaire I would identify more closely with conservatism then any other political movement.
Therefore I allow myself to be identified as a conservative.
