Thanks for the advice. I want to make sure it's clear to you and everyone that it's not my intention to point the finger. It's unfortunate in that respect that aviation is such a small community.
It turns out from reading all the replies that the instructor was probably right anyway. The context of the conversation was a brief on Vmca and I think they were trying to allay my nerves about the Vmca/Vsse demo. I have spread my initial multi between two flying schools (not ideal but unfortunately unavoidable) both with vastly different philosophies regarding multi-engine training.
I appreciate all the responses, negative and positive alike.
