What you're saying is true only when the "hammer" in question has a precise goal in mind, e.g. give voting right to women or abolish slavery. You can't compare a confused movement like BLM to any of the previous progressive movements that have worked in the past. This really isn't about social progress. It's simply the textbook scenario of a society being subverted and an attempt to take power from another group. Every single goal of the BLM group fits the description.
