"Ken said that in all his time as a Labour member he had never heard anyone say anything anti-Semitic
Apart from, as a random example, that Hitler was a good man who won an election in 1932 and merely wanted to expel Jews from Germany, and it was only later than he "went mad". So now, in Livingstone Land, Mein Kampf (published 1925) is not the work of an eliminationist anti-Semite, but in fact of a democrat who only wanted to help establish Israel a few years early, and Hitler's rise to power wasn't an autocratic coup, but was "winning the election". It was only later he went mad, and fascist, apparently.
That's the sort of embarrassing fawning over the Nazis as being basically on the right lines but getting carried away later which you find on Stormfront, and Livingstone's claims to "reading a lot of history" can only be understood to mean "reading a lot of books by David Irving and, for light relief, Eric Nolte". It's not quite holocaust denial, but it's getting pretty close to it: it's the claim that the holocaust was not the systematic expression of the policies of the Nazis, but a later aberration, brought on by circumstances (Nolte) and done without Hitler's knowledge or direct instruction (Irving). One does have to wonder why, if Hitler were such a cuddly friend of the Jews in 1932, that Dachau was opened in 1933 and the Nuremberg race laws were enacted in 1935, but once you're an apologist for HItler, I guess those sorts of problems are easy enough to gloss over.
This is a member of the Labour NEC speaking. He's apparently booked on Question Time for tonight, which I presume won't happen.
On a more serious note, if such a thing is possible, you don't have to have spent a lot of time around people with early-stage dementia or suffering from the effects of small strokes to see that Ken is, in fact, unwell. He perhaps always was anti-Semitic filth, but if he was he was a smart enough politician and had enough of a filter to keep it on the down low. He's now completely unhinged, and that loss of social awareness as to what you are saying is the sort of thing that is an early symptom of dementia, as people (rightly) suggest over on Relationships when parents are described as having sudden changes of social skill in their 70s. He's 70, and has lived hard; it would hardly be surprising. His heart is as vile as it always was, but his mouth is now a sewer for reasons he can't control. We should, in part, pity him. "All political careers end in failure", and all that.
