You see, I didn't know you were a MtF. I questioned certain ideas, not your identity - because I didn't know it at the time.

Knowing it, maybe I would talk differently; exactly because I didn't mean it as a personal attack (although that was your interpretation).

Anyway, I didn't mean to offend you, and I apologize if you felt this way.

I respect you as a person, even when I discard and reject your opinions. Maybe you conflate the two, but I see them as two very separate things.
