Because despite pointing out exactly why I thought it was true and explaining Obj-C's various dispatch optimization tricks and how they still left an optimizing compiler/runtime with a far greater challenge, the response was generally, "you have no idea what you are talking about". Thanks to Dunning-Kruger, it's quite difficult to be sure if they just can't be bothered to explain what I don't understand (maybe performance differences arise elsewhere... maybe there were far more sophisticated tricks in the modern message dispatch code than I'd come to understand... though it seemed unlikely they'd be so significant) or its the other way around. Empirical evidence would seem to point strongly in my favour, but you'd think that'd give people some pause before making such statements.
