In the German state of Bavaria, dozens of people are in 'preventive detention' because they might otherwise engage in climate protests, specifically around the car industry exposition IAA in Munich.
Apparently possible for a month there...

This is specifically Bavaria. They also recently found out that their vice president has a past as a Nazi and the reaction of their president was essentially "Oh no. Anyway...". So, yeah, if you considered visiting the Oktoberfest, maybe reconsider.
Eh, I don't expect random tourists to be locked up by the fascists, nor do I necessarily expect the not-quite-fascists to distance themselves from the fascists, just from losses in the tourism industry.
I'm mostly just saying, there's tons of places you could be traveling to and "drinking beer with fascists" isn't quite as attractive anymore.
