Interesting! But as the notice says BLM is not one group.
And in fact it is a shame that anybody named them as it was quite clear that the march was not organised by them (as a quick google would have shown).
Also, irrespective of who organised it, being central London any march if bound to be piggy backed on by the SWP who are so over the top in needing to be shown as woke. (You can tell by their mass produced placards when they are around.)
And there is nothing they like more than to have an online example of them being woke, so the police directing marchers past the women speak out event must have felt they had won the jack pot. Of course they would want to be seen attacking women who have the nerve to say women are biological females.
And 99% of the march just walked past.
So this was more like a real world enactment of a vertual twitter spat ie a tiny % of people (twitter is one of the least used social media platform) picking a fight on twitter. Just self aggrandising egos.
Lets hope the next event is free of other events so that it can be an opportunity to make direct contact with other women - surely the most important aim.
Not getting derailed by self publicists.
