Of course you do. So do most people. Thats whey extremists get elected. Extremism is easy. It saves having to think about issues. You just pick your position, read up some literature, and then regurgitate back the pre digested pap that passes for political discourse in the western world these days.
Tell me. If there is no doubt where someone stands on an issue, how is there any chance that they can be persuaded otherwise?
If I vote for someone based on his stands on an isssue, why would I want him to be "persuaded" otherwise?
