Lie 1: Satanists approve of evil
Satanists dont approve of evil. We just dont think masturbation or gay sex is evil. What Christianity defines as evil is very different from what Satanism defines as evil, which is why Christians fall under delusion that anyone not following their values follows complete evil.
Lie 2: Satanists want to kill Christians
Historically, it was Christians who did the actual purge and killing of not just satanists, but also witches and almost all other religions. They eradicated thousands of religions in Europe where they took their position.
If we are to accept Christian version of history, then each of old religions for some reason wanted to kill all Christians. But this doesnt make sense if Christianity was peaceful religion and Europe had thousands of religions already who had no reason not to accept another peaceful religion.
The actual truth is that Christians were consistently attacking all other religions, which is the only version of the story which makes actual sense, since there is no way to explain how Christianity out of thousands of religions became primary target of all other religions.
Lie 3: Satanists dont have moral standard
Christians often think that only their morality is objective morality, which basically means if you are not Christian, you are immoral and evil.
So Christians openly declare all other religions as evil.
This further supports the idea that Christians were trully attacking all other religions throughout history, because they began from a premise that all other religions are evil.
There is no way to live in peace with people who you consider evil and corrupt.
Satanists, as well as anyone else, have moral standard. Its just different from Christian moral standard.
However, Christians see anything different from their view as evil, which is why Christianity is a morally flawed religion since its designed to attack all other religions.
