Popular movements almost never are the ones to actually institute policy, only influence it, so there's not really much advantage to finding compromise at the level of activism. It's not BLM or the Defund movements job to write legislation that actually achieves their goals, and there's almost no chance what they argue for won't be watered down anyway. It's best to think of any popular movement as directional - for sure there are individual people in the Defund movement calling for 100% abolition, and others calling for demilitarization, or redirecting of some funding - as of right now, they want the same thing as far as first steps go. If they're successful in redirecting some funding away from police, the non-abolish crowd will move away from the movement and they'll become increasingly irrelevant when it's 10 anarchists arguing for no police instead of massive protests.
