In short: Republicans are Nazis.
Nah, just our policies, beliefs, attitudes, behavior and demeanor... We want to enslave children, destroy the economy, kill old folks and club baby seals...
It's pretty hard to have a reasonable conversation with a Democrat nowadays... Almost all that they seem to understand is ad-hominum attacks. They wouldn't know a real Republican if they saw one, they only understand caracatures. I guess that's what happens when you get your news from the Daily Show.
