The people banned from that thread were (a) well known troll, and (b) someone who signed up specifically to post in that thread, who was essentially also a troll, and likely with an axe to grind about how outspoken the band have been in the past about this subject.
Even taking aside that I don’t particularly believe this place is an echo chamber, it’s just a lot to see a staunch “free speech defender” (never a great starting point imho, but again let’s take that aside) take the side of two pieces of internet trash and people come out on side of that?
Like I said, it just felt very very weird given the context. There was no nuanced discussion shut down.
