ALM is a censure of BLM, which was a convenient nominative signpost for a rally banner that was aggregating a significant amount of violent and destructive riot activity in the name of it's cause.
You can argue that "if it was violent, it wasn't BLM doing it", but when you had the movement being used as a cover the way it was, and look at the bigger picture, it should start to crystalize.
ALM is a reminder. Yes, BLM. No one reasonanable questioned that. What chafed people, is the assertion any one group should be treated differently period. The fighters for civil rights of the last century plus fought hard for equality. There's this new push for equity which comes with extra baggage of "others should have to be subjected to exceptional treatment to compensate for historical treatment*. That is just racism, or segregationist thinking in another wrapper.
That is what ALM is a reaction to. Equal is hard. Equal requires work. Equal requires the unreaonanle among us to refuae to be pushed aside, and that's okay. Just... Be judicious with what gets enabled in the meantime, and don't provide cover/outlets for arson/robbery/vandalism/destruction of infrastructure at the same time.
Obstruct, be heard, yes.
Divide, destroy, no.
All lives matter. And if someone feels like they aren't mattering, odds are, the bunch of people trying to make heads or tails of quantitative and qualitative evidence as to the claim, and information propagation is work, and takes time, and has mo guarantee of success.
