Your information isn’t quite accurate.
The right wing counter protesters were not a contingent of the March. They showed up to protest against the March. They were moved on from the Cenotaph in the morning (after many being arrested as it was a mile away from our route) and then they came looking for trouble and attacked the main peace rally all day along different parts of our route, trying to get to us through the police & barriers and were still doing so in Parliament square in the evening. I was there.
”On Saturday morning, far-right counter-protesters had clashed with police near the Cenotaph in Whitehall, ahead of an Armistice Day service. Scuffles broke out as police attempted to stop a crowd of far-right activists, Islamophobes and football supporters carrying St George’s flags marching along the Embankment towards Whitehall shortly after 10am.
The group, which had been chanting “England til I die” pushed through the police barrier, with some shouting “let’s have them” as officers hit out with batons. Further clashes took place in Chinatown with counter-protesters chanting: “You’re not English any more” towards officers. The Met said officers had “faced aggression from counter-protesters who are in the area in significant numbers”.
Tommy Robinson, founder and former leader of the far-right English Defence League, was seen among the crowds protesters.
There were further clashes into the evening, including a crowd of roughly 150 rightwing protesters in Parliament Square. According to the BBC, an offensive chant about Allah was chanted and a Palestinian flag was ripped up. By Saturday night, police said there had been 126 arrests and nine officers had been hurt during the clashes.
Met assistant commissioner Matt Twist said the violence from rightwing protesters towards the police “was extraordinary and deeply concerning”. He said the “intense debate about protest and policing” had contributed to an increase in tensions.”
Of the Pro-peace/ceasefire march of 300,000 people it was reported
”While the pro-Palestinian demonstration was peaceful, many of those present chanted “from the river to the sea”, the saying identified by many as indicating support for the elimination of the state of Israel. Police also said they were investigating at least five allegations of hate crimes including antisemitic and racist chants and placards displayed on the march.”
Assuming all 5 allegations of racism/amtisemitism were true (and we reported all that we saw), then that represents 0.002% of propeace protesters that could be construed as pro Hamas and antisemitic. Meaning that 99.998% were not racist, were not antisemitic, and were not pro Hamas/terrorism.
