Did I say they did? The GP poster just made a unilateral assertion, and I was trying to point out a case where the assertion is false. That case doesn't apply here; but nor should you implicitly accept the GP's conclusion (that ESR should be kicked out of this community), since one of the premises used in their argument (that all FOSS "must be kind") isn't true-as-stated.
When you want to do something as serious as exiling someone from cyberspace, you need a high standard of rigor in your arguments; and you need to be wary of thinking you can "read through" rhetoric to "what they clearly meant", without having false claims made for rhetorical purpose still affecting your judgement.
I invite the GP to restate their argument with more precision, and see if it still sounds compelling.
