I'm on the right and the only thing I can think of is when some conservatives use "liberal" as a derogatory term but I don't think that's nearly as bad as calling someone racist or white supremacist, when they're not. All that does is shut down any chance of a meaningful discussion.
The term Socialist is widely thrown about, directed at Democrats. It very, very rarely applies. Even Bernie Sanders isn't a Socialist, even though he pretends to be one in name because it bolsters his attempt to appear radical vs the status quo. There is so little actual understanding of what Socialism is these days, people widely believe the Scandinavian nations are Socialist (they're all mixed economy welfare states, not even remotely Socialist, with most of the economy privately owned, vast private wealth very common, and functioning on free market principles with hefty doses of regulation).
It's somewhat understandable that people can't keep democratic socialists and social democrats straight. But most Democratic figures they call socialist are just so far from any of that that it's unbelievable.
Forgive us - "conservatives" largely support the world's most famous birther, a man who criticized an American judge based on his ethnicity, and attacked a gold star family because they were muslim. If they're not racist, then they're totally cool with it? Or just really stupid. Forgive me for making that conclusion.
