So long story short, in my fantasy football league, a rule was written in such a way that I and at least two other people interpreted it differently from the way the commissioner intended it to be read. I wrote an email to the commissioner saying "Since I and at least two other people interpreted this rule differently, I thought I would explain how I am reading it." However, he got very angry (extremely short temper) and told me that I do not speak for other people, so I should not presume to.
I did not name the people who interpreted it differently, and specifically chose not to reveal their names. Also, I know they saw it my way because we all had discussions about it.
Given this set of facts, have I actually spoken on anyone's behalf?
