MrsGrady - is is good to see how the reasonable and intelligent are rallying round over this, leaving the unthinking or the racist clearly exposed for what they are. I wasn't sure about Corbyn either (and I'm Jewish) but for me, the first signs that things were not as they should be was when highly intelligent, long-term supporters of the left whom I respected started deserting the party in recent months - everyone from Robert Webb to Maureen Lipman. So don't feel bad about being taken in - there's no reason anyone should have expected this from the left. No reason at all. This lengthy thread is really an attempt by all of us here (trolls excepted) to make sense of how this change could have come about. It is (to me, anyway) almost incomprehensible.
I've been reminded very strongly through all that's been happening of the distinction between those who supported the Nazis and those who didn't, as described by Sebastian Haffner in his superb book on the rise of the Nazis, Defying Hitler - which I recommend everyone to read if they truly want to understand that era (and yes, I am aware I am breaking my own rule on not invoking Godwin's Law here, and desperately wish that that period of time did not present helpful parallels to where we are now).
Haffner describes very clearly how some people are driven by loss and failure into hatred and scapegoating of others (eg Hitler), whereas others, such as himself, were able to find more constructive and self-critical ways to deal with their emotions. Well worth reading, as I said.
And thanks.
