"In the words of a friend of mine -
Whatever you think of the guy's politics, you have to admit it's kind of amusing that the man most hated by the British conservative right (who generally claim to adhere to Christian values) just now is a bearded anti-war activist whose main stated aim is to help the poor and disenfranchised, has a definite downer on bankers and the ultra-wealthy, and whose initials are JC. :-D "

I don't believe he is hated by the Conservative right, he seems the person most likely to ruin the chances of the Labour party at future elections. As such I can imagine that some of the people paying their £3 to get a say in the Labour leadership elections may well be Conservatives hoping to see him win.
