If in the original post you had put something like ** I"m not sure if this is the correct forum to post ** that is not passive.. It's stating you're not sure, and it's ok to be moved to the correct forum if needed.

since you didn't include it, and it was moved and then you asked why, and followed that up with "I had a right to ask a question"... I still don't think that is passive, but he could perceive it as you being defensive...which it sounds like he did...

either way.. I don't think you did anything wrong really, and at best it was just a misunderstanding..
