I am not certain whether I agree with that; I might, actually... I certainly would if it were in private, or in context. However, that doesn't make the argument "if you think X is Y then you should check out Z: it is so much more Y you will stop calling X Y by comparison" a useful argument: you can almost always find more and more extreme examples, and eventually you are saying "at least he's not Hitler; you can tell the difference, right?".
