It is still the Labour Party Lumarei and I really do have trouble with the childishness of name-calling when it comes to someone purporting to want an adult discussion.
I assume you were a member of the Labour Party and are now feeling disaffected with them. I'm not sure what they could do to please you. They have voted for the same person, isn't it twice, and it seems he is what the membership want.
Is it a bad thing to be a "radical"? After all, Margaret Thatcher, whom many seem to hold in high esteem, was certainly one. As it seems to me, have been all the conservative leaders since her to some degree or other.
Where, oh where, is there any proof that the Labour Party want Communism. On the left/right political spectrum I can give you more examples that show the Conservative Party moving to the far right than I have ever seen of the Labour Party moving towards Communism. Think of those poor One Nation Tories who were kicked out of the party. Look at how many Tory MPs are not going to stand again because the party has left them and what they have always believed in.
We are back to rather puerile when you say you will not talk to me because of the leader of a party I have no say over and to which I do not belong. So perhaps the only thing to say is "goodbye".
