This all points to Corbyn simply wanting everyone to get along and for there not to be any arguments, and Sultana being someone who knows that it's vital to take action and set out a position. Also, it was reported several times that Corbyn is wound up by her doing this.
No idea how true that last one is: I suspect he asked politely for her to take into account others, and the press lied about how mad he was. But Corbyn let the Labour right stay in Labour and sabotage him, and I suspect something similar may be afoot with the Gaza independents in the future.
Adnan Hussein has already gone on record saying that he sees the party as a vehicle for conservative Muslim values, and if it becomes that then he will kill the party stone dead. So taking all that together, I assume Corbyn is the one tolerating bigotry for the greater good, and Sultana isn't.
Also, Sultana came out defending trans rights straight after Hussein started demanding segregation for trans people. And Corbyn has said nothing but hugged him closely at events today. Incidentally...
A friend went to one of the events today, and said they were clearly stage managed so only supportive activists and local councillors got to ask questions, a bit like how half the Labour questions at PMQs are planted by Starmer's whips.
That suggests to me that this vehicle may also be as tetchy, controlling and terrified of being challenged as Labour is, and that the whole party-democracy thing may not be as democratic as Corbyn is making out. It seems we'll have a voice only when he lets us.
