There you go again. Can you provide some examples of the "open anti semitism by socialists" from the Labour party, please? I'm gonna need some quotes on this as so far it's been hearsay. I'm not arrogant enough to think there's no anti-semites within the Labour party - just as there will be in the Conservative party, UKIP, Brexit party etc.
Are you only concerned about anti-semitism or do you feel that racism and bigotry in all forms is wrong? The Prime Minister of the UK and leader of the Conservative party has made numerous anti-Islamic comments - does that mean we can expect the "physical persecution" of individual Muslims any day now - or is it more the case of the fact that you're so opposed to Socialism that you've convinced yourself of something that a "sane" and "objective" person wouldn't believe.
