No backlash from me; I'm a Labour Party member who has accepted that Jeremy Corbyn is the democratically elected (twice) leader of the party. However, I am dead against deselection.
Due to our first-past-the-post election system, both Labour and the conservatives are effectively coalitions anyway; in Labour's case between socialists and social democrats/liberals, in the Tory's case between free market capitalists, and old school conservatives. There is no need for Corbyn to remake the party in his own image - every leader tries to, but it's seldom possible or desirable, as Tony Blair discovered.
For the record, I think Corbyn is far more of a democrat than Blair ever was.
