the way i see it, this is one of the many symptoms of a general cultural trend, the gradual revocation of liberties acquired by the lower classes over the course of XXth century
it started somewhere around 2000 and becomes more noticeable every year
what you are allowed to do, what opinions you're allowed to hold and express - the spectrum gets narrower and narrower
as a result, the degree of edginess that was the norm in the 80s and 90s has become pretty much off limits
and there is no shortage of volunteer thought militias to enforce the new limits,
because this way one can "protest" and "fight evil" and at the same time risk nothing, because what he really fights for is the mainstream, government-approved, corporation-approved, mom-and-pop-approved discourse
and on top of that, not only can you feel good about yourself because you are supposedly changing the world for the better
but you can also enjoy power over other people - the people whose spaces you invade and remodel to your taste
ironically, this is what could make industrial/noise/PE goons relevant again
there's no point in being offensive when you actually offend no one, and this is how it was for quite a long time
