To introspect a bit, I think the rote regurgitation aspect is the lesser component. It's just rude in a conventional way that isn't as threatening. It's the implied truth/authority of the Great Oracular Machine which feels more-dangerous and disgusting.

It’s clumsy and has the opposite result most of the time, but people still do it for all manner of trends.
