As an American, I obviously can get behind it, but I can easily see how a declared goal of superiority of others would rub those others the wrong way (and possibly prevent their contribution)
>a declared goal of superiority of others would rub those others the wrong way
So what? Does that change anything in how things work in reality? Everyone knows it, so why pussyfoot around it?.
Why are people nowadays so sensitive about saying the truth of how things work? Have people been coddled that much that they've can't handle reality? A good life lesson is that the world does not revolve around your feelings.
It's not my feelings mate, if you don't live outside the US and have not been subjected to their unipolar attitude you will probably never understand and there is literally nothing I'm going to say to convince you of the objective reality the rest of us face.
