The problem is, it makes it far too easy to brush it away from a point of ignorance and people who consider themselves devout will never look into it. It serves the interests of Christianity and edginess more than it serves something that would identify itself as, say, biblical scholars. Plus, if they become Satanists, which you may consider a joke label, people who would have had a degree of legitimacy in the eyes of Christians who might be convinced to begin questioning their beliefs can now be much more easily discarded because “Oh, didn’t you know, he’s a Satanist!”
Trying to argue for the term is akin to arguing identifying as a Nazi not because you really support WWII Nazis but want to reclaim the term of socialism within the national perspective as something that can be realistic without the hate, racism, eugenics, and populism. You would be doing more harm to the point you are trying to argue for. It will get views, yes, but are those the views you want?
