politics is more the domain of punk.
if it were actually about promoting a political message or religious message then it'd be Hitlercore
Nazicore
Satancore
Pagancore
Norsecore
whatever
But BM, even NSBM, isn't about actually promoting a worldview or religious view.
It's just about being deliberately offensive or shocking, which that aspect is metal rather than punk.
Doing songs to deliberately cause fear, shock, or offense.
That's metal.
