honestly earth sucks too much to worry about the things that get the happy neurotransmitters going in your brain. Like maybe don't support awful people or buy into terrible ideologies, but no one's gonna know if you torrent and watch a harvey weinstein film or the west wing or something.
I would like to stress that it's still not okay to like NSBM under any circumstances
I don't know what that is but I trust your judgement
I just looked it up and the top result was national socialist black metal. So don't listen to nazi music even if you like it.
I've seen people defending listening to NSBM with reasoning like this depressingly often, which tells you how shitty metal fans can be
