There was a brief moment where “all lives matter” had no clear meaning, where the slogan still was up for grabs, where the fascists were still starting to rally while BLM was already in full swing. If, at that juncture, BLM had had the wherewithal to, as I already said, switch to chanting “all lives matter” without skipping a beat the few fascists already using it would have looked like actually supporting BLM. They would’ve backed off.
