Which policies are they then? Examples please.
Politics in the real world is all about compromise; it's the art of the possible. Which is why the doctrinaire student politics of Corbyn is fine in a protest movement but useless in the leadership of a party who would like to govern.
Furthermore, the absolute conviction of idealists who refuse to accept they are anything other than 100% right on %100 of the issues, is pretty sinister. It's what the far left has in common with fascism (that and a tendency to conspiracy theories and anti-semitism).
Exactly!
