Said it before and will say it again, he completely failed to learn the very obvious lesson from Rotherham (and similar abuses in other authorities) that people need to be able to feel comfortable raising safeguarding concerns without fearing they'd be labelled racist and have their careers and reputations adversely affected, when he pushed out one of his ministers for talking about this issue.
He puts his politics, and maintaining his self created 'inclusive' image over reality and the safety of women and girls.
He utterly failed to handle the anti-semitism debacle. it's no coincidence that people with openly anti semitic views now feel at home in the labour party under JC.
Honestly means being able to look at yourself honestly and he doesn't appear able to do that. as shown under the whole anti-semitism episode. He appears to lack any ability to self-reflect.
Politics means being able to listen to and work with people with different views from you. HIs whole career has involved doing the opposite. He's an activist not a political leader.
I have come to actively dislike him. I don't respect him.
I will not vote Labour whilst he is leader.
