It's true though. Some people from the left marginalize conservatives and their ideas by attempting to link them to Hitler, racists or other such nonsense. Then righties try to slam any kind of liberal idea as a mental disorder or a way to get the government to control every facet of someone's life.
It's just silly. Debate ideas and policies from a logical POV. I recently watched a great debate on YouTube between Noam Chomsky and William F. Buckley. What's striking about the debate, filmed during the 60's, is how civil, and respectful, these men were even though they're completely different ideologically. They didn't sit there and call each other names for an hour, which is what happens nowadays.
