I had no suggestion that people converse in first order predicate logic.

I did suggest we are all smart enough here that we can have rich discussions without committing clear logical fallacies. HN is special in that the majority cares about thoughtful discussions and reasoning. Because of this I often read the comments in HN before the article, where historically the signal to noise ratio is quite high.

There are plenty of other forums for rhetoric or fun conversations.
