I mean, this is certainly plausible, but I don't think it's that simple. There are all sorts of examples of degrees of one thing or another, yet is there any other example where a major portion of the public suddenly lost all perspective to the degree that they believe things that are literally incorrect (and mock those who are not)? It's not just that people are exaggerating things, the fundamental beliefs are such that it is considered not possible for a nationalist to not be a racist, if not worse. Rarely are such outrageous and objectively false claims challenged, and frequently any challenge is downvoted to net negative.
