Both times it has come up, you have said, essentially: "I am right because I've been to college and I therefore know more than you." While that may indeed be the case, you haven't said one thing to back it up other than repeating variations of that same theme. I see no facts, no nothing. Not even any speculation. The only numbers you have posted have been laughably wrong, which before they are proven wrong you hold it above me as if you are a superior being. Its also pretty obvious that you were trying to have a serious debate before I came in and challenged your points. This tells me that you either have no points, or simply don't like it when people prove you wrong.
And if you don't think the Internet is Serious Business, stop bringing up serious topics, and then when challenged on them say "I was only having fun." If you continue to bring up how cars need more fuel mileage, no matter which topic they are in, I will continue to argue it. Its as simple as that. Not because I'm after your blood, but because I would truthfully like to know whether you are just a clueless know-it-all, or whether you actually have insight on the topic. Your points on hybrids tell me the latter, but everything you have said about this topic tell me the former.
At the same time, for someone who is constantly calling people hypocritical, and constantly wagging fingers of shame when people condescend and insult each other; you certainly seem to do it. All the time. In fact, I'm sure this will lead to you badmouthing my opinions where you don't expect me to look. A technique that I will admit to have used, but at the same time I don't constantly remind people that they are breaking the AUP, so whatever.
Furthermore, if you think I have some kind of vendetta against you, I think you need to let the hot air out of you head. I debate with people when I think they are wrong. I don't care who you are. I don't care which college you went to. And I certainly have a better use for my time than following someone around on the internet to prove them wrong. I don't pick fights simply because I don't like a person, and I am far too indifferent to your attitude for it to matter if I did. I've had epic debates with members who have far more contrasting personalities with me than you do, and it hasn't made me dislike them. Me constantly arguing with you simply means you are constantly saying things I disagree with. Nothing more, nothing less.
