I could, in fact, make a strong, scientifically sound argument that the sky is NOT, in fact, blue. It's highly dependent on how you want to define the property of having color. Pick something slightly less ambiguous as your obvious argument. 1+1 = 2, for example. But please specify that we're working in a base larger than binary, in which case you would of course be wrong.
I'm nicer than you, though, since I warned you that I'm going to pull some totally irrelevant point out of my ***, like how I meant to deal in binary the whole time and 1+1 never did equal 2. And then act as if I'd won some great victory because you had fallen into the common logical fallacy of only working within the numerical system you were familiar with, rather than the one that was really relevant to this discussion forum, since we're using the internet and computers really can't understand a 2.
