To emphasise this, how pathetic would it be for Labour supporters to say the Tories can’t complain about Corbyn anti-Semitism, because of their handling of the Windrush scandal, and the racism involved? You have admitted that an older guard of Tories have a racism problem, so using this logic of hypocrisy, we can just dismiss Labour anti-Semitism concerns.
We shouldn’t, because problems on one side do not justify problems on the other. There is no way we can improve things if we just shrug our shoulders and say “it’s fine, the others do it.”
