I can't speak to the OP's meaning, but it has to do with the way people are persuaded. >Personally I’ll stick with a firm insistence that Covid presents serious risks, vaccines are safe and effective, and the inability to comprehend a scientific paper This comes across as based on the assumption that people are rational and, when presented with evidence, will weight that evidence accordingly. Unfortunately, that's just not how humans evolved to extrapolate about reality. Anyone who's ever debated online knows that simply presenting information isn't an effective way to persuade somebody. We're emotional creatures more than we are rational ones. There's lots of research on this (my favorite domain for this subject is behavioral econonmics) but a quick, interesting and related read that touches on this topic is Scott Adams' Win Bigly. To the OP's point, speaking in condescending tone, regardless of the 'rightness' of your point, isn't likely to persuade someone because it will illicit an even stronger emotional resistance.
