Yup, twitter was a cesspit yesterday in terms of antisemitism and Islamaphobia.
Rachel does need to consider the factions that she's encouraging as many of those people are only supporting her so that they have an "acceptable" way to be openly racist towards Muslims. As soon as it is no longer useful they'll return to their standard operating procedure of blaming Jewish people (note: I'm not trying to be antisemitic, but these supremacist sorts hate all minorities).
I had the misfortune of listening to that space and a user with the number 88 in his user name (a neo nazi reference to the letters HH aka a phrase that the Nazis used) arguing that the "White man" built Australia and all minorities need to leave
Some very dangerous people are coming out if the woodwork.
