That's great you're motivated to learn stuff. It's good that you want to share your knowledge. Attitude still comes through a computer screen. You type words and they convey that attitude. There's no need to get into a lengthy "I'm right, you're wrong" exchange. If you believe something is correct, show your reasoning and see what people have to say about it. If someone disagrees, fine, they disagree. It's only someone else on their computer, they don't know you and they don't mean to insult you. This is a pretty chilled out place, no need to be the supreme master of automotive theory or anything like that.
