I don't think this is a joke, since it's from the same email address as someone that was looking to commission some Harry Potter props a few years ago.
Dear Sir,Having returned as a penitent to the Catholic Church, I write both to denounce your website as full of evil, Harry Potter as full of devilry and the wickedness of magic and to implore you to do penance likewise in the Holy Church.
Incidentally, my <redacted name> relation was more distant, a lie of false intimacy and another sin.
<redacted name>, the worst of sinners.
As some of you are aware, I'm an ordained minister. My enthusiastic embrace of fleshly delights in my younger days is long past, but rest assured I'm as much a sinner as anyone, . That said, I believe having a Harry Potter wand is the least of the debits in my spiritual ledger.
If I am informed otherwise, hopefully many, many years from now, I will do my utmost to update you.
