I don't know what to say about your prickly confused paranoia. I have no need to 'slander Jews'. If I were to criticise a Christian fundamentalist would I be 'slandering Christianity'? If I were to criticise a Jihadist would I be 'slandering Islam'. Should I be told to shut up?
Look, the guy you have supported here is open in his support of Kahane and the JDL. That's just the territory you occupy.
