I totaly understand your position. There are so many people I would like to talk to and either say sorry or "O.K. lets have that same discussion. and I'll tell you where your pobably right".
I left after my questions couldn't be answered and I had to deliver talks, feeling like a hypocrit(sp + 2 glasses of wine).
I am very fortunate to have a group of school friends who allowed for my theocrastic expressions at the hight of my apostalizing and helped me through my departure.
People are very understanding, they would have known, much more than you at the time, why you were saying what you were saying. I'm pretty confident that if you did get the chance to meet these people again, and start to explain you actions, they'd laugh and say "yeh, I know" before you could finish.
Thats been my experience.
Steve.
