Beer Hall Putsch?
Need to read your history.
At that time Germany had entire military units wondering on their own - the Freikorps. The Beer Hall Putsch was VERY serious.
The poor PEGIDA folks don’t have access to these sort of resources, and the Polizei are probably going to come down on them like an avalanche. Then the courts will use every Thought Crime law on the books against them.
Pray for them.
