So, the Satanic Temple is non-theistic and not tied to any religion and confession. You could basically be Christian and be part of the Temple, even if it sounds contradictory. It's not about following a (single) deity, it's about the symbol and about freedom and compassion and empathy.
Therefore, the Satanic Temple does not limit me in the number of deities I'm allowed to follow, so I can follow and hail Blahaj and Lucifer at the same time. Also, it's a trans flag, so it combines Satan and Blahaj.
