Tanith - given you've said you have experienced violent racism yourself, I'm not really clear which bit of what I said offended you or why you seem to fail to get my reference to 'people wanting me dead'. Racists aren't, sadly, cuddly people who just say a few mean things to get a rise and then sod off. Within living memory, six million Jews (including many of my relatives) were murdered in a Western European country that was perfectly civilised, much like this one in fact. The Germans weren't uniquely bad, or mad, or even uniquely anti-Semitic - the anti-Semitism in Germany pre-Hitler was pretty standard for Europe at that time, and in fact Jews were probably treated better there than in most European countries.
In more recent times ie within the last couple of years, Jews have been murdered in France and Belgium (not a million miles away from here) for nothing more than being Jewish - Jews going shopping, Jewish kids at school, Jews out visiting a museum. I cannot pray in a synagogue without a permant guard, because the risk of violent attack is recognised. If you still don't 'get' why the risk of violent attack is real, then I don't really know what to say.
If I have learnt one thing from my parents' sad experience fleeing Nazi Germany, and from the experience of my relatives who did not manage to get away, it is that when anti-Semites say mean shit, you take them seriously. Hitler didn't start by murdering Jews, because, well, ordinary Germans might have been a bit shocked. The process started slowly - by subtly (and then increaingly unsubtly) dehumanising Jews, by low-level attacks and attacks on those who stood by them. Until one day, after a few years of this, Jews could be attacked and even murdered with impunity, and no-one turned a hair. Some even welcomed it.
The way to prevent another Holocaust - the only way - and indeed to prevent all racism, is zero tolerance of discrimination. Whether you find it offensive is really neither here nor there - if you don't think Ken's comments were in any way offensive, that speaks volumes about you, but you're not really the issue here. The issue is that Ken made unsubstantiated and unsubstantiable accusations about anti-Semitism and Zionism and Jews. And he needs to be brought to account for it. And low-level anti-Semitism everywhere, but particularly on the left, who really ought to know better, needs to be stamped out.
Racism is NEVER acceptable. Whether the victims are Jews, or the Irish, or whoever. Why I need to explain this to someone who has themselves been a victim of racism, I genuinely have no idea, but presumably you do.
I still hope (and believe) that you and I are on the same side in this fight. At least if what you say about yourself is true. Not clear why you're trying to pick an argument with me. I have no interest in one.
