Right-wingers are America’s “deadliest terrorists” if you exclude the deadliest, most catastrophic terrorist attack ever perpetrated on U.S. soil, according to data highlighted Wednesday by CNN anchor John Avlon.

Avlon’s overall point is confusing enough, and it is not entirely clear why he and his producers thought it would be a good idea to air this comparison of jihadi and right-wing body counts on the 18th anniversary of the Sept. 11, 2001, terrorist attacks, which claimed some 3,000 innocent lives.
