I think she’s saying that those condemning the Sydney guy are hypocrites, for being the same people who also condemn Israel and in doing so making her feel unsafe in London as an Israel supporter. But it’s hard to say.
Also it’s not a very consistent position as she seems to be ignoring the reason why people take issue with Israel, I.e. opposing the genocidal violence Israel is committing against the people of Palestine.
My personal favourite is to break from staring after 30 mins, exclaim, “Hang on, we’re going about this completely back to front!” then spend the next hour deriving from first principles, only to arrive back at the original problem, but now with slightly different notation. At which point I realise that all I’ve done is get myself back to my starting point… Then it’s back to the staring.
