Still correct, though! 
Making Mistakes
It is correct, but it is wrong at the same time. King vs King & Rook is result of mistakes made earlier. And we are talking about opening and middle game here. As much as I am mad that I can not prove you wrong here, that is not what we are talking about. Now if I say that King can not win vs King and Rook, that would be wrong too. I hate you. Say you are wrong.
I hate you. Say you are wrong.
This is my favourite bit of your post!
I won't say I'm wrong, because I am right. But that doesn't mean to say that what you say is wrong.
OMG, that is so stupid.
