Of course there are. But the interesting thing about OMMP on Belief-L is that it’s a kind of meta-fundamentalism, under which Christians, Wiccans, Deists, Muslims, etc. can all band together and be intolerant to anyone who doesn’t agree with their shared worldview.
I would disagree on the “all.” For example, plenty of people are looking for a way to feel smug, or to get out of hell for free, or to let them do whatever they please and feel assured that Jesus already paid the bill.
The thing I found most problematic about OMMP is that first of all, it was very narrowly defined, compared to your definition. (And I agree with your definition, to the extent that what I would say that “legitimate” religions are about answering the question, “what’s going on here?”) The second problem was the arrogance of it, by which no one could be permitted to disagree: fundamentalist Christians who felt that by definition Jesus was not the same as Allah would be told “no, you idiot, you worship Allah just like the Wiccans do, and you just haven’t figured it out yet.” This would be especially galling when, having pedantically lectured people on the true will of God, they’d further lecture the fundies on the “hubris” of saying that they, as Christians, would go to heaven when they die. After all, it takes real hubris to claim you know God’s plans for you, right?
