No, you have never made any such statements, derogatory to either race or religion. I don't think this signature is either, more a political statement than anything. My opinion.
True, it's a point about a regime that I abhor and their racist policies, I am obviously anti racism and anti ethnic cleansing, sure I think the Irish government are the biggest bunch of corrupt f**kers in the world, serious unashamed cronyism in Ireland, it's not as if I think the Israelis are bad and everyone else is good. Besides all my sources on this subject are either Jewish or Israeli Jewish, hardly racist methinks. I changed my sig anyway for another factual quote
