Conservative vs Liberal

My desire for this blog originally was to if possible open a dialog between liberal and conservative thought. It bothers me to read articles and blogs where each side pounds on the other. It seems to have no point other than the person doing the writing gets to vent their frustrations. But I seriously question whether a dialog between conservatives and liberals can take place. The conservative blogs and articles I read are just too vitriolic. It really seems all they want to do is spit poison. They don't seem to have the slightest interest in a dialog or in finding the truth. I realize making such a statement is itself inflammatory which one could argue makes me guilty of burning the bridge to the other side. But it may be that liberals and conservatives can't dialog. David Limbaugh recently wrote that the Democrats are questioning the choice of Joe Biden for VP. That sounds like the liberals, always asking questions. I don't see conservatives questioning anything, at least not in public. If that is indeed so then no dialog is possible between the two sides. Upon reflection I suppose I could describe conservatives as doggedly holding on to their opinions with no interest opening their minds to new ideas or change. I see liberals as the opposite. I hope I am wrong about this because America at this point seems to very polarized in so many issues.
