I am amused by those who believe it is "slander" of someone to repeat or post what the person himself said or did.  Donald Trump is a master at this allegation whenever the press shows a video of what he actually said or did.  Now we have Rodne's apologist doing the same thing.  If there was any slander here it was done by Mr. Rodne with his racist comments about Muslims.  And being a member of the Marine reserves does not give him the right to make appalling comments about whole groups of people.  He said what he said, and he was rightly called on it.  
By the way, a statement cannot be slander if it is the truth.
