I don’t know what memes are… but I probably should look it up… Anyway … a thought to analyze later …
For better or worse, the genes of a culture are its sacred books. Without genes, what results is a loss of identity, existential ickyness, and culture-less-ness or some sort of a generic culture.
Example : Aurangzeb

Of course you have to probably define or lay out what culture is, and that’s a pain in the lower extremities.
