American politics is so polarized....

I disagree with your premise.  I question that the GOP is really made of up hard-liner conservatives.  You claim the Democrats are functioning as the party that just opposes their opposite, but I think that's the GOP.  I'll give the Democrats this credit--I think they believe what they support.  Right now, a lot of what the GOP has advocated is just done to oppose the Democrats.

If the Democratic Party stands for something, I have yet to learn what it is.

The whole in your logic is that it's based on assumptions that are themselves based on anecdotal evidence, whereas the counterargument is based on objective data.
