This was inspired by my post yesterday about how the metal community is full of chuds and other varieties of reactionaries, so I've been compiling a list of all the bands that I know are at least not reactionary. I'm only including extreme metal bands because there's more ambiguity since these bands aren't as mainstream as something like Black Sabbath, Metallica, or Judas Priest.
This list doesn't include bands that are 'apolitical' because the list would be way too long and it would be 99% death metal bands that most people already know. I'm also not including any bands who fuse metal with other genres like Rammstein or most metalcore bands unless the metal influences are extremely strong, not because of "metalcore not true metal" but just because many of those bands don't consider themselves to be metal anyway.
