Sincerely, that's where I think you are wrong. I'm happy you enjoy your Debate 101 class or whatever, but this is a forum for D&D discussions, this is not debate club or whatever. People don't care about 'debate tactics' because they are not usually trying to convince you about anything, they are just saying what they think. Applying logical debate 'techniques' and 'rules' to a D&D discussion is meaningless, presumptuous and rude.
Also, facts don't exist.
Except it does. It might have no bearing as debate tactics or whatever, but common sense does exist. After all, it's a concept that has been studied for milenia.
