Are you liberal or libtard?

I'm an independent who leans about 70% liberal on social issues, and about 50% liberal on economic issues. The conservative platform has its merits, and having all conservatives shouted down as bad people -- along with the other regressive things some liberals do, makes me furious, both as someone who slants liberal and as an intelligent human being. It makes people look like fools when they use ad homenem attacks against their intellectual foils, and it hinders actual progress. Shouting people down as racist without talking to them isn't progressive, it's regressive.
