What if most of the individuals in group X aren’t Y, but everybody (or almost everybody) who’s Y is in group X? If there being individuals who are Y is bad in some way, then should we blame group X? Should we hold group X responsible for the influence of that minority of individuals? Most of the individuals in group X aren’t Y—that’s the hypothetical that we’re working with here—but without group X there would be no (or almost no) individuals who are Y. Something genetic-memetic about that group results in a minority of individuals who are like that, and that minority may have a disproportionately strong influence.

By analogy: In a beehive, the majority of the bees are workers: ~90%. There’s also a minority of drones: ~10%. And besides the workers (which are sterile females) and the drones (which are males), there’s one queen (which is the non-sterile female). The workers, the drones, and the queen work together. Without the beehive, which is the “group,” there would be no queen, which is the special “individual.” With no beehive, there’s no queen. If you don’t want there to be a queen in your backyard—for whatever reason—then you shouldn’t want there to be a beehive. If you kill the queen without killing the beehive, then the beehive will spawn another queen and you’ll be back to where you were before.
