Ed I would not consider you a dinosaur, maybe a bear with a sore arse from time to time, but never a dinosaur.
I understand 100% your stance with regards to topics where you "go off" for lack of another phrase.
As for being different on the internet as opposed to person to person, in Ed's case, certainly. In person he would not hold back, he has learned great restraint over the net. As for myself, I bite my tongue many times online, where as in person, I would tear someone a new one.
