The original weirdness comes from thousands of years that humans saw these other animals with their animal boobs dripping milk into the mouths of their babies, and decided that we need some of that non-essential nourishment at any cost.
That’s why it’s weird. And it only gets weirder when we have to build up industrialized processes to support an obviously unsustainable and harmful process because…the percentage of the population who can stomach the non-essential infant cow juice want it so badly?
That weirdness has been happening as long as we’ve been stealing milk from cow babies.
and decided that we need some of that non-essential nourishment at any cost.
But it was essential. Drinking cow milk was such an evolutionary edge that genetic analysis indicated every lactose tolerant person to have the same ancestor where it first occured some 6.000 years ago.
Drinking milk was not essential, as evidenced by your very mention of people being lactose intolerant to milk, a simple fact that proves milk is not essential.
neither is hot water, having a non leaking roof or a functional health system. Do you want to skip on any of these as being weird? it was a huge advantage and quite dominant in human genetics.
