The Antisocial Socialist

Nonsense. Let's talk bodycount.

Over the last 20 years, how many actual dead people are the direct result of left-wing violence in the U.S.?

Clearly, if you group by ideology, you get something like this:
Right-wing Islam: ~3000
Right-wing Christian (or non-specific religion): ~200
Left-wing (all or no religion): ~0

There are left-wing Christians and left-wing Muslims, but I think it's telling that they are uniformly criticized by the right-wing (and even mainstream conservatives) in their own community for being too pacifist, too tolerant, and too respectful of women.
