This is the word we need to use when dealing with anyone spouting any socialist idea.

Don't water it down, try to protect sensitivities, or attempt to identify with their feels.

Say, bluntly, "That's fucking retarded. I thought you were smarter than that bullshit."

Then explain why it's retarded, and keep repeating just how stupid retarded it is.

Ridicule works, and communism is retarded, so it's just the truth.

Let's detard America, personally, one retard at a time.
