This is a tricky one.
I have no issue with the trader being banned - according to the piece, she contravened the council's laws regarding its stalls, so no problem.
I do have an issue with the reason why she was criticised - for selling Knights Templar mugs.
It's true that their symbols were 'culturally appropriated (ha ha!') by the Nazi Party, but that does not detract from the fact that history is what it is, and pretending that it is not is an insidious censorship that should robustly be resisted at all costs.
I worry that one person is able to 'take offence' and cause a situation where a trader is sanctioned for selling legal merchandise.
Even allowing for the large Muslim population in this area, I am not at all sure that the majority of Muslims would appreciate 'offence' being taken on their behalf in this way - or the reaction of the council.
I think that the council do not come out of this well.
