I've reread the entire thread, especially your posts, and I'm not sure why this was brought to your attention as rude but not to the rest our attentions? I, for one, really enjoyed the back and forth discussion. While heated, it seemed to me like we had a good discussion without swearing or defaming anyone. I spent a lot more time on the board for those few days, eager to see what someone else's opinion was. I would hope that heated discussions such as these are not discouraged as long as we all explain ourselves clearly without mudslinging.
So if you have to apologize, so do I. I'm sorry. (No I'm not - it was fun!)
