Of course he believes every word he tweeted, but he's "sorry" --"sorry" because the outcry was becoming a real threat to his job security, and he did manage to bleat that on consideration it was "insensitive" to post it during Holocaust Remembrance Day.
Sizer has a long history of anti-Israel rants that can only be explained by that pathological condition with which we are now all dismally familiar. It would be fascinating to know if, in posh Virginia Water (I remember it well, and the house, and the hostess) he's had a chance to discuss the fate of Christians in the Middle East with his congregation.
Thanks for posting this. It's important to know that the ideology that spawned the Holocaust arose in Christian Europe and still has resonance there.
