Actually, if you read the bill - just 3 pages long, and most of it on just defining the ammendmant - it only states that religious freedom will be protected. If anyone can imagine a discrimination against homosexuality in it, they can imagine discrimination against anything that involves the beleif of any religion - that includes cults.
I think that’s the point; the law is so broad and general it could be used to defend anything at all. Freedom of religion is already protected.
