This is so true, and I hadn’t thought about it before. Christians (especially fundamentalists and evangelicals) are often badly misinformed about witchcraft and Pagan and polytheist religions. As a result they will often believe whatever confirms their existing biases.

They tend to read “analyses” of Paganism and witchcraft written by Christians, which are usually wildly inaccurate.

Occasionally one meets a well-informed Christian who has read the work of Ronald Hutton or other serious scholars.

I have also noticed that Muslims are frequently well informed about Paganism, and even if they’re not, it is usually possible to have a sensible conversation about it with them.

Credulous journalists (who are often very ignorant about matters of religion) will also publish any old nonsense from people claiming to be ex-witches, because they are happy to sell newspapers with sensationalist trash.
