I think there's a pretty distinct line between being called a racist and a paedophile. One is a crime and the other is not; implying someone is a paedophile is literally accusing them of crimes they have not committed. There was a recent case with Justin Bieber I think, where he sued two women who made up allegations (on Twitter) that he had raped them, and I believe that was successful. Being called a racist is unpleasant (if you aren't one, anyway, so that doesn't apply here) but it isn't false witness.
