This is tangential to your point, but what would you say to a utilitarian who says:
“Evolution (memetic evolution, that is) has instilled in me the idea of that I should linearly value the welfare of others regardless of kinship, regardless of what instincts I got from my genes.”
Since such a belief is pretty potentially disasterous for the genes—so: how come it got through the memetic immune system? Perhaps this is a case of meme evolution outstripping gene evolution, resulting in virulent memes that can memetically hijack people’s brains. However, many seem to have working immune systems—and can resist this meme. Do the utilitarians have weakened memetic immunity? What can have led to that? Were they not taught about the risks of memetic hijacking in school—or by their families?
