I think it would be fair to say that the public is concerned with both, but more actively threatened by the fact that their house might have its windows smashed in because a protest happened to occur near to them. Like it or not, we tend to be more frightened of things that affect us personally.

People don't have their windows smashed. Even in Hamburg, the most violent protests in the last decade, only upscale stores and expensive cars were targeted, all of which were insured.

That's not to excuse those actions–personally, I think they're counterproductive to whatever the cause may be. But people really aren't afraid of these protests. I was actually in Hamburg at that time, and even though I was walking around in a suit & tie, I freely walked right through the protest hotspots without even a hint of aggression directed at me.

FWIW also in most cases where there are antifa "riots" in Germany, it's usually known beforehand where they will happen so most people know better than to park their expensive cars there.

Of course that doesn't make vandalism okay, especially when it harms private citizens (even with insurance the damage can be a financial drain for shop owners) but it puts the extent into perspective when you compare it to neo-nazis who actively try to harm human beings or entirely destroy their (already quite modest) livelihoods.
