Read those problematic witchcraft books, read those Wiccan books that people don't agree with, read those books that people can't stand. Why? So you can read them for yourself! That way you can understand why people feel the way they feel about certain authors and books. And also, you can process how you feel about them. To also take that a step further, read the books everyone raves about. I have books that I like, and I have books that I got half way through, and I haven't touched since. And that includes books that some people truly like.
Another example of this action is when I went to church with Jehovah's Witnesses. Jehovah's Witnesses are not very well liked in my area. Their beliefs have made them banned in several countries, and folks in my area tend to avoid them as much as they can. But one day, I was invited to go to one of their meetings on Sunday. I kept my comments to myself, I followed along in one of their Bibles, and I even sat through like a for one for all study session where everyone participated. The topic was, "What Would Happen If We Get Banned". It was like 40 question booklet thing, that everyone took turns reading like we would do in grade school.I sat through over 2 hours of discomfort because my butt went numb, and I was bored, but for them this was a serious issue, and I tried to be respectful.
Why would I do that? Because didn't want to be another broken record in echo chamber. I wanted to see for myself why people feel the way they do, inside and outside of the congregation. And now I also have opinions of my own.
