"All X are Y, and their denial proves it" seems a very poor argument to me. By its very nature you can't really disprove it.

A kid arguing they are not a kid is a very kid like thing to do is my point. Kids always want to convince people they are not a kid. I'm not 3, I'm 3 1/2. I'm not a kid, I'm 22. Jokingly, when you start trying to convince people you are younger is when you're probably old enough to be considered an adult.

If you told an 80 year old they're a kid they would also tell you they aren't. There is no proof by irony.
