Careful with generalizations. Characterizing Booth, McVeigh, the Kennedy assassins as lefties might require some major distorting...
McVeigh was an exeption. I think he was an anarchist, and thats just a messy place to be
Which Kennedy assassin? Oswald or Sirhan?
Oswald was a missionary communist who lived in the Soviet Union for a while. Sirhan despised RFK for supporting Israel.
I’d wager they both might be to the left of most of us here.
