Not to rain on your parade or your revisionist history--but

JFK was killed by a mentally deranged Communist wannabe.
RFK was killed by a Palestinean disgruntled with his target's views on Israel, and other perceived injustices he was angry about.
Malcolm X was killed by a couple of members of The Nation of Islam, a group X had formerly belonged to and renounced.

None of the above were killed by people of the right. Only MLK has that dubious, sad distinction.

The clouds having cleared, you may now revise away.
