Saying that BLM set out as an extreme left wing group is as inaccurate as saying because Women's March set out an agenda that was incredibly woke, left wing and some say anti semitic, means that all women's groups are.
BLM both here and in the states was a name adopted by local grassroots activists. There was no agenda.
But as with Women's March, and much appreicated by the media who are too idle to do proper reporting, a group set up a web site claiming they are BLM and put out an agenda of the politics of the 2 or 3 people who did that.
I find it hard to believe that because a web site says it is this that or the other than any one on this forum would take it as fact.
And one of the main groups who infiltrated or appropriated the BLM logo was the SWP and its affiliate Stand Up to Racism.
I dont know what the agenda is of the many genuine BLM grassroots groups are because they are drowned out by the usual suspects who the media aggrandise because it is easier to do that.
And dont forget this is exactly what they do to women's groups and feminists activism. They will report that Sisters Uncut is THE feminists groups, and so on.
There is no basis for making sweeping generalisations about a movement based on the content of one web site.
And anyhow the march in Hyde Park was not a BLM march. It was a totally different organisation.
