It's not real, in the comments the author provided a link to the supposed bill... it's about putting a plaque on a building. And I can't find anything credible to back this up.
I don't doubt that there are people out there who'd love to fall back to the days of persecuting people for witchcraft (not that most of the people who were burned as witches back in the day were actually witches/pagans, most were victims of mob mentalities and personal vendettas), but this looks to be probably fake.
Also, there is no anti sorcery law or legislation in AL, I live there and I made sure after reading that because I follow Druidism and am a member of a local Druid Grove. No clue about AR
I don't see this becoming an issue at all. Freedom of religion is a big part of our government, one of the few things they seem to be sticking to. If anything, things are better now for nonChristians than they ever have been.
