The confrontation with Marc Wadsworth was not antisemitic. You can see for yourself the exchange in the video.
He said:
// “I saw that the Telegraph handed a copy of a press release to Ruth Smeeth MP so you can see who is working hand in hand. If you look around this room, how many African Caribbean and Asian people are there? We need to get our house in order.” //
Ruth Smeeth described this as
// “I was verbally attacked by a Momentum activist and Jeremy Corbyn supporter who used traditional anti-Semitic slurs to attack me for being part of a “media conspiracy”. It is beyond belief that someone could come to the launch of a report about anti-Semitism in the Labour Party and espouse such vile conspiracy theories against Jewish people.” //
She interpretted the exchange as a traditional anti-Semitic attack when it was nothing of the sort. People have obviously reacted to her distortion and been nasty to her on facebook. Why any so called intelligent MP takes notice of anything on Facebook is beyond me.
