The arrogance comes in the way you deliver your argument and insist that your preference is the only valid choice, regardless of any difference in conditions; it has nothing to do with the science.

I took the same Human Factors class that cites the same decades-old studies that you're pushing as ultimate truth; all of that science was done when multi-monitor setups weren't even supported, let alone common. I have no problem agreeing that a universal menu is optimal for certain sets of conditions, but that doesn't mean it's the one true way for everything.
