Nah, it's just the US reinventing the German Antiqua-Fraktur dispute from more than a century ago, where only Fraktur was appropriate for expressing serious Germanic ideas. A sans typeface is un-German... ahh, un-American!

Of course, a couple of decades after that, Fraktur was declared too Jewish and thoroughly eradicated, killing among other things the sole remaining independent strain of Latin-script handwriting (other than the dominant one invented as a book-copying aid by the Italian humanists, thus “italic”).
