Where did I say TST isn’t a religion? TST can be a religion without depending on belief in a deity (or deities) or some other omnipotent being. That doesn’t make it a non-religion, but it certainly does oppose most other existing religions.

From their website’s FAQ:

The Satanic Temple believes that religion can, and should, be divorced from superstition. … To embrace the name Satan is to embrace rational inquiry removed from supernaturalism and archaic tradition-based superstitions.

Your conflation of my statement with delegitimization of TST as a religious organization is quite a reach.
