One is free to be factually wrong, like claiming that Australia is not
a continent. (I've seen that, in a quiz game.) Definitions can most
certainly be incorrect.

Until negative numbers have been taught, you cannot. Once they have, you can.

You can get through a lot of life believing that mass is conserved,
but technically it is not, as can be proven. Ergo it is a lie to claim
that it is, which fits into Steven's post.

There are a lot of those kinds of posts now, and I like the style.
(That's why I made my own take on it, about PEP 8.) Yes, okay, that
last one "You're kidding me, right?" doesn't technically fit into the
concept, but seriously, if nobody had told you that some people are
nameless for 5+ years, would you have guessed that that's the case?
