Ever hear of RCF?
Wahabbists, perhaps--but they point out, explicitly, WITH documentation, some of the problems.
www.rcf.org
I have a co-worker, former Catholic himself, whose mother is still Catholic and belongs to this organization. I can't say I necessarily agree with what they're about totally but after hearing from my co-worker his complete lack of knowledge of the Bible before leaving the Church (he personally felt this was rampant in the Church), maybe RCF isn't so bad.
