No, I don’t think that’s true, and I don’t think you could produce a single example.

Keep in mind that stating a fact and dogwhistling are not the same thing.

Exactly, you don't think it's true because you don't believe they're facts, you've been radicalized into believing they're "dogwhistles" (a term only used by radicalized people, by the way - if you keep hearing dogwhistles, you might just be a dog.)
