Just guessing here, but you tend (not always) to come across as argumentative/combative, and I suspect that some just don't know how to approach you.  Like I said, just a guess.  Do you think that you "stir the pot" here from time-to-time?  I appreciate your efforts on the board, but I will say that on any board that I have ever spent time on, PM was supposed to remain PM and I'm sure others would agree.  I don't see any threatening in the tenavee message.
