Maybe you should leave this argument to the big boys then. Mattocks and billcihak, when asked, will actually post their sources when asked. Billcihak and I have disagreed on multiple points of multiple topic. But there is a mutual respect that allows us to debate and yes, on occasion, he has changed my mind on things. You are of the opinion, judging from your words, that your opponents will never change theory mind no matter what information the encounter. So that begs the question: why are you posting in a debate forum? If you aren't actually trying to change people's minds, then what is your intent? Do you just like being contentious for the sake of contention? Do you just put your views out there so you can cackle, crow, and say , " I told you so" should it turn out you happen to be right? Or are you just that impressed by your own typing?I really hope this isn't the case. I am rather hoping you are a valued debate partner.
