We’re only confident agriculture has existed for ~5,000 years. Hunter gatherers don’t have the kinds of complex societies that can do organized coercion in a sustained way over generations. Even if you restrict yourself to post agriculture arranged marriage is far from universal and there’s no evidence I’m aware of of a sustained breeding programme selecting for some trait among humans.

Not random and selectively bred work at very different speeds.

Extrapolating from the few extant hunter gatherer tribes that never achieved complex civilization to the tribes that invented agriculture is obviously wildly erroneous.

You are speaking about sensitive matters you know very little.

People were never "bred", arranged marriages were never genetically consistent across even one generation, let alone many, and your continued ignorant speculation aligns disturbingly well with how eugenicists described human evolution through the early 20th century.
