.I can demonstrate high value
.Ok, then demonstrate high value

I forced him to, at least internally, acknowledge that he cannot demonstrate high value and he chose to resolve the resulting cognitive dissonance by firing off a bunch of ad-hominems and easily disproven claims then running away.

You can call that what you like. I'll call it the first 4 stages of grief.
