John Wilkes Booth

John Wilkes Booth was the assassin of beloved President and anti-slavery liberal Abraham Lincoln. He was an angry cooperhead aka "peace democrat" (when that meant "pro slavery", of course) and also an actor who tended to find it difficult to tell the difference between stage drama and real life. At that time the Republicans were far more anti-slavery than the democrats and many Southern Democrats were KKK members.

Boothe supported the Confederacy in the American Civil War and hoped killing Abraham Lincoln would prevent freed slaves getting the vote. This is why we have/need (depending on where you live) gun control. Just look what happens when you "give a Conservative a gun."
