Not quite. Usually a funny little quirk of the human mind takes over. The word German somehow transforms into Nazi. It's odd how often that happens when Crowley is involved.
Of course Crowley courted controversy during his life. He loved to shock and play centre stage. But you can only shock the shockable and gull the gullible, and the surprise (or maybe no surprise) is that it still works to this day.
Why do so many people think Crowley was an evil Satanist? Mostly because the vast majority of people, whether they admit it or not, still secretly fear a supernatural bogey man call the Devil. It's this silly superstition and it's vice-like hold over peoples minds that causes people to get stuck on Crowley's supposedly evil reputation as a Satanist. Why else would you hear people constanlty saying that they fear the Thoth Tarot and the black shadow of Aleister Crowley that hangs over it like some sort of evil vapour. It's hilarious.
I see Crowley's reputation as a kind of litmus test. If you can't see past the stage show antics you won't get anything out of Crowley or his writings at all.
