Ad Hominem

Doesn't have a point of view
Knows not where he's going to
--The Beatles

In debate or discussion, ad hominem means responding to arguments by attacking the person. Making it personal. Name calling. Bigot, racist, hater, mean-spirited, stupid, insensitive, etc.

When people respond to your arguments in ad hominem fashion, chances are you're making progress toward truth.

When you respond to arguments with ad hominems, you're getting nowhere.
