¿Conspiracy?

¿Why is everyone these days trying to persuade me: that icky/nasty things--slimy salmon eggs, so-called "red caviar" (such as, with bated breath and grimaces of disgust, one uses to bait one's hook, when fishing for trout), utterly raw sashimi, and blood-reeking steak tartare (with raw, runny, sulphurous egg yolks)--taste good and are good for me? that Neanderthal males knew how to talk, and had (comparatively, I guess) enormous penises which were irresistible to our homo sapiens sapiens great-grandmothers? that the 2020 presidential election offers some kind of meaningful political choice to the electorate?
