Genuinely, it's not only christianity. I despise islam, buddhism, hinduism, (idr the name of the jewish faith). Every myth adds a layer of separation from reality. Would people be so eager to decline life saving abortions and HRT if they didn't expect a second life? Would there be so much hatred without the group mentality of a name? Genuinely, religion takes away individuality, it creeps up into your brain.
And also, satanism is about satan not as a god of sorts, but as a role model, like El Cid Campeador, a rebel who fought unfair authority, (the church, the fascists, anything) represented by god to gain the freedom to live outside the unfair rules of faith. Like I like the term satanism bc it makes the pearl clutchers clutch their pearls, but I could also be called "Überschmen Nihilist", "Sophist", "Cynicist", "Absurdist" or "Hedonist".
