Your sentences are quite difficult to read so I apologise if I'm misunderstanding, but I think it's good to remember cases like Saudi where religious fundamentalists were placed into power by Western powers. These days we see them as representative of the Islamic world but it's largely our own doing.
I'm aware that there are non Islamic "oil countries" of course and I don't think the GP comment was equating oil with Islam. It's just something that does happen in other contexts and that we should be aware of when speaking, because there are very real real would consequences.
