I do know that many GLOs were founded on certain religious beliefs (Christian, Jewish, etc.), but I've never heard of a situation like yours. Whatever happened to diversity?
I think the problem is that a lot of people hear the word "witch" and either freak out or automatically think "
weirdo!", which isn't completely fair. As you said, any self-respecting witch would never hex someone so that their hair products didn't work.
But people are afraid of the unknown, so while I don't think the reaction of the chapter is justified, I can understand it.
I'm sorry I don't have any good advice for you because my chapter never had a situation even remotely close to something like this, but I do wish you luck in sorting it out. You did say your sorority sister was a
Christian witch, didn't you...so what are they all up in arms about?
