Because he is controversial exactly because of the political implications of his discourse, and I do think apolitical people may be pushed towards the right side of the spectrum inadvertently be reading his seemingly innocuous advice. And although this is a complex topic that I cannot go into in detail right now, I do feel the need to point out that there are not two axes, but in fact there are infinitely many axes, and we choose to focus one or two depending on the context. Perhaps this is what you meant when you said there are two: that we should not look only at right/left, but also liberal/authoritarian, and in this sense I agree. But I think it’s important to be aware that these are merely useful conventions, and that there are potentially many other axes that we could think about.
