Read and understood, we probably agree about most everything here and discussing it further is probably suboptimal.

I'll make a few clarifications that I don't think you'd argue with too much:

It has been written about extensively. Again, this wasn't a PhD thesis. In fact, it's been written about extensively here on LessWrong before, notably "Tsuyoku vs. the Egalitarian Instinct" by Eliezer. I suppose I did assume some familiarity with the material that other readers might not have, and could have cited that as relevant prerequisite reading.

I had read the post and recognized the concept, but a link to it would have primed me more for looking at similarities/differences between the phenomena you and he discuss. Consider adding one?

Some of this behavior certainly seems mean-spirited and malicious to people. Many examples available if you honestly can't think of any.

I can think of many examples, but I can also think of many examples that don't seem malicious, in fact most don't, and since you're proposing an explanation of the class of behaviors, it seemed absurd to think that anyone would think that malice was an explanation. But upon reflection this was severe typical mind fallacy on my part.
