All Selection is Individual – But individuals do demonstrate selection as groups

All Selection is Individual – But individuals do demonstrate selection as groups. A word game.
I have this argument with Jayman (@JayMan471) because the ambiguity is causing unnecessary nonsense.
It’s the only thing I’ve ever disagreed with him on. And that’s because (a) by the terms used in the field all selection is individual – no other selection exists: ie there is no group selection.
However (b) this is a word game. All selection happens at
the individual but humans are both extremely sexually adaptive (sheep, goats, horses, holes in things, anything), status seeking and predictive based on all sorts of criteria. Meaning that groups DO select by criteria even if within the group all individuals are selecting by that criteria.
Neoteny is the most pervasive critiera, is highly selected for in women, and eventually spreads to men.
Small isolated groups tend to demontrate more selection and variation. Groups with lots of neighbors have a harder time. Why? Because while you need about 1500 for healthy falsification of bad mutations, you also neeed to keep that number small enough to allow the spread of positive selection.,
