Yeah, I think that's normal... A few recent examples from here is a band Luctus, cancelling a few concerts in Spain because antifas from there found an interview with vocalist of the band when he was 15 years old and amongst answers about his favourite lessons in school and so on, he mentioned that from time to time he listened to NSBM. This is of course very dangerous and might build up fascism pretty quickly.
On the other hand, there is a guy, local activist, who is known to be ill with schizophrenia. Years ago he started B&H in Lithuania (or at least he claimed to start), then he became football fan and now he is a very big fighter against fascism. Few years because of his massive diarrhea of emails to Korpiklaani managers etc. they cancelled their show, also problems with Skyforger and countless other bands. The point is - because of the thing that he is medically confirmed retard, he lives with his mum who gives him money to buy vinyls and he has plenty of time to fight against threats of fascism that might appear on the internets.
