Let's see
He excuses racism within the party if it suits his agenda (Neil Coyle, Ignoring the Forde Report)
He cosies up to the right wing factions of the party and allows them a free pass, for example his support for the Hindu council, a organisation set up by the bjp to act as a voice for modri government and stoke tension between hindu and muslim communities (east leicester being one).
He has practically ditched every leadership pledge and renaged on most of his comitments that got him voted in.
He has allowed a local level witch hunt of members both left wing or just who disagree with some of his policies and issues suspensions on the most tenuous reasons, while others have been allowed to carry on.
His fence sitting on trans issues which has led to misogyny against some women in the party and also left trans members in limbo on what the party actually stand for.
His stance on the strikes was out of touch with memebers and the public.
His re-employment of that worm mandleson
His hypocrisy knows no bounds
Not arsed about corbyns suspension just so it's clear my dislike of starmer has fuck all to do with that clown
