At this point I don't see any difference between the two. Modern religions are shaped (warped, really) by the larger organizations that control them.

Sure, the concept of "spiritual/non-scientific belief" isn't a parasite in and of itself, but even if the existing organized religions ceased to hold their sway, and people treated religion as a personal thing without centralized authorities, I still don't see an end to (for example) people trying to get their religious beliefs enshrined in law. That's parasite behavior.
