Sugiyama doesn’t get the ‘separare the art from the artist’ treatment because he used the clout/ money he got from the music he composed to perpetuate his shitty views.
This is kind of the stance I have taken as well. If the creator is an arsehole I can kind of live with. But if they actively use the money I have given them (or even a share off) and then use that money to actively spread their misery, then I can't support them.
