And indeed your point is that it [The Orthogonality Thesis] is not obviously true, not that it is obviously false. So if I were to downvote your post because I thought your argument was silly or obviously wrong, that would be equivalent to stating that it is obviously true.

Not all things that are obviously true once stated are immediate to think of.
