What is your point? Why are you crying over bog-standard anarchist stuff? If you think this is dangerous, perhaps you should start looking at the right-wings equivalent; which has been openly advocating for violent disobediance against the government, with guns.
It's already dangerous for the groups targetted by both the state and fascists and has been for decades, it seems to me that you are uncomfortable with it potentially affecting YOU and YOU prefer to remain out of it, but there will come a point where your passivity is no longer an option if you wish to live in a non-fascist, free society.
Unfortunately history has shown that people like you will sit out for as long as possible, going so far as to defend the very people that ultimately wish to harm you, even as the fascists mobilize and actively recruit over the internet, planning more attacks.
But what's the point in me explaining it? How many more attacks by fascists must we see, how many more deaths must we bare before you open your eyes to the threat growing in our countries? These people will not stop and our governments refuse to do jack **** about them, is it any wonder why Antifa exist?
