France will shut down gilets jaunes protests —the whole protest— if a black bloc is present.

Nonviolent protesters should not tolerate the participation those bent on violence. If the protest degenerates into violence, its moral force is lost. If only part degenerates into violence, the rest does not deserve to lose its moral force, but plutocratists will try to blame them all.

That's exactly what the plutocratist French state is trying to do now.
