I guess what I mean that we all argue hypothetically all the time. Maybe the problem you have about other people is precisely that. They argue hypothetically (often believing they have proven facts), you don't. In a way that makes you superior in any given situation. An argument with you can't be won. Many people become aggressive when they sense that their opinions don't hold water.

And actually here I am hypothesizing. I once had a very intelligent, matter-of-fact, perfect wife, and she started abusing me for being so given to speculation. So I am the opposite pole, I guess.
