Regarding wanna be censors. There are smart ones and stupid ones as in every path of life.
There have been people questioning before shows that were ok and had lots of fun once they broke their sense of guilt and we got to know each other better since they actually cared about listening the music, read the lyrics and meet the people, something almost none of these people do... and others that react in pavlovian reflex.
I still think the worst thing happened to camerata mediolanense, when Bern self-claimed justice league attacked the venue without noticing that the singer is a gay-bear (actually there with his boyfriend), and the rest of the project were family-people. I was gutted when it happened.
all expensive gear (and club) got trashed, but gladly some of these got arrested and had to pay all the expenses etc. I am not a big fan of legal justice since I had my degree of problems with it and I think jail, etc are NEVER solutions for teenagers - unless for very dodgy crime -, but for once I was happy to contradict myself and was quite glad to know the hammer of the blind goddes crushed the culprit.
Thing is, whoever does extreme stuff should always bear in mind that going against the world does not include being enjoyed by everybody and social antibodies could always react violently, be this the legal system istelf or different form of liberal/conservative-minded people.
It is not a matter of communism, antifas, fascists, christians... these behaviours are mostly common feauture of people with low self-esteem with a lot of time to spend on the internet, often getting money to fund social trusts/university studies/etc need a reason to exist (no nazis/no money/no books published/no university work/no party) and whose fire power is often made of young idealist good-doers that have no time to get deeper into things and understand contraddictions, ambiguities, etc.
It happened with many cultural expressions (more relevant than underground ones), whenever a boundary was reached, a holy cow was shot and an old taboo broken, and as usual with age, those who were once victims turn into overzealous slaughters. we might become as well in a few years, who knows?
what can you do? be always prepared for the worst, never excuse yourself, never explain yourself too much to them -they are going to use your words against you- , always keep in mind they have no authority on you and you owe them nothing. if they attack fight back, if they shut down a gig, well that is sad. It is always good anyway to show when they lie in your own terms. contraddict their lies in your own term in interviews, your own web sites, etc.
Just look at the protesters outside the london gigs last year... nature has already been cruel to them, the maximum you could do offer them a tea and pat their shoulders.
