I don't know about "most" cases, but that sure as hell isn't the case when and where I grew up. I don't know anybody my age who grew up in the same household as their biological mother and biological father, except for my ex-wife, whose parents ironically divorced after we got married. Among my peer group, having a Dad and a father is the norm, rather than the exception. So, no, as a matter of fact, I can't understand, "sure" as you might be to the contrary. I can understand that that might have been normal for you, but I can't understand why you would assume that that was normal for me as well, instead of taking what I said at face value?
As far as your comments about me, personally, I don't actually "like" to argue about anything. I will openly admit to two particular character flaws (one, I'm a pedant, and two, I'm an abrasive, confrontational person, both on the internet and in real life) which cause me to get into a lot of arguments, but I don't enjoy arguing with people. I don't even enjoy talking to people. If anything, I'm borderline-OCD in my inability to let things drop: I don't get any pleasure out of it, at all.
