the point here is just that you’re wrong.
this may seem like a ridiculous claim. a person can’t just be wrong; s/he has to be wrong about something in particular. you’d be right about that, except for just one problem: you’re wrong.
but i’m not wrong, you might say, and i can prove it. i say you can’t. you say, well, how about 2 + 2 = 4? i’m not wrong about that, am i?
and the reply is, yes, obviously. because 2 + 2 can only really equal 2 + 2. you can define 2 + 2 to be equal to 4, but that’s where you start to go off the tracks.
