A Metzitzah Debate with a Chabad person

Disclaimer: I do not believe the individual in question is a fair representative of Chabad, and I do believe Chabad representatives in general are a lot more open-minded and caring.


Over the recent holiday, I had a conversation with a person who considers himself a Chabad rabbi (I'll grant his Chabad-ness, but I don't give much credence to his being a rabbi). This was the first time I encountered him since he told someone who had hired me as a mohel that I was unfit to serve as a mohel. (The father followed his advice and cancelled the hiring)

I wanted to know why he felt this way, and we proceeded to have the following conversation, which focused mostly on our approaches to the concept of metzitzah.
