Okay this is a neat (likely fake) story, but the reality is that this is, objectively, terrible advice. "Don't dabble with elements, commit 100% to a thing even if it makes no sense and is an actual assault on the eyes. You aren't allowed to like something or use accents, your things must be only the thing you like right now at this moment or they're complete SHIT." If I don't love it, I must HATE it or it's absolute trash.
It's even worse to relate this to politics. Don't weigh and evaluate the merits or shortcomings of arguments from a multiple viewpoints or stances, pick only the extremes of one side or the other and make everyone that disagrees think you're insane and maybe want to kill you.
See only black and white. View the world only in extremes.
