Why do conservatives do this?

I am a conservative and here is my opinion on your question. I think that when someone has such a strong opinion on a matter, whether liberal, conservative, independent, communist, etc, they tend to utilize whatever information they have to further reinforce their original opionion. I can give you many instances when liberal arguments turn hypocritical. I think this is partially the problem with our state of affairs in general. This thought process leaves little room for compromise on issues. Liberals and conservatives need to come to terms that not everything they think is the absolute truth on matters. Surely, there are liberals and conservatives who could committ to at least admitting that they could be wrong on certain issues.
