I think value claims are more likely to be parasitic (mostly concerned with copying themselves or participating in a memetic ensemble that’s mostly copying itself) than e.g. physics claims, but I don’t think you have good evidence to say “mostly parasitic”.
My model is that parasitic memes that get a quick and forceful pushback from reality would face an obstacle to propagation compared to parasitic memes for which the pushback from reality is delayed and/or weak. Value claims and claims about longevity (as in your example, although I don’t think those are value claims) are good examples of a long feedback cycle, so we should expect more parasites.
