Despite the ongoing problem of LLMs passing as human (and before that, https://xkcd.com/1019/ etc.), it is entirely possible they're 100% sincere.
First, remember that a lot of people voted for Trump despite all thay he said in the election and all that he did last time around. What he says must resonate with a lot of people, or that would not have happened.
Second, anecdotally, there's someone I used to know back in the UK who was absolutely convinced that Brexit would be a success, to the extent that at one point me simply saying "no" to some claim he made resulted in him shouting "that proves we should do it!" (or similar, it's hard to quote exactly from memory, especially 9 years later). Cambridge graduate, did the maths olympiad in their youth, still acted that way.
And third, it's very easy to get anchored on something that was once true, and not update as the world moves on. When I was a kid, "made in China" or "made in Taiwan" was not a sign of quality, but "made in Japan" was; but one of the films of my youth was Back To The Future, and one if the few things you can allow even fiction to inform you of are cultural beliefs, like 1955 Doc Brown being written to expect "made in Japan" to justify component failure.
