The Power of Swear Words.

There's nothing funny about it. You specifically omitted the age I said they begin learning it.
At no point did I say eight year olds were in kindergarten. This is not Shenanigans. Do not spam.

Lol, sure, fine.

It's kindgergarten level sociology most people begin to understand intuitively by five or six and have mastered by eight.

So what you're saying here is that this is a very elementary concept that most people start understanding without even thinking about it at the age of 5 or 6. Then you conclude that this fairly simple concept is then mastered just TWO or THREE years later by individuals that can barely comprehend the vastness of the size of the world. That's what you say, and that is completely ridiculous and thus deserving of my laughter.

Perhaps these children are able to understand on a very simple and uncomplicated (far from mastery) level the power play that can be engaged in with words. Do they understand the extent of those words? The implications and intricacies of them such as a mastery of the topic would demand? No, of course they don't. Most adults don't have a mastery over this subject.
