Corbyn holds every one in contempt. Not just the working class. All of us. Anything that is mainstream popular consensus he rejects. And he has rejected so much that all of us have been covered by his rejections very quickly indeed.
Labour are socialists. Corbyn is a socialist. The masses aren't. No one else is outside of oddball lefties.
And the clue most certainly isn't in their name. None of them do any Labour at all. They sit around in palaces all day.
