People don't talk in first order predicate logic, it is just not how it works. Insisting on it is silly I think. Once in while mentioning "Ha! got ya, you just committed logical fallacy ${Latin_term}!" works. And is certainly very useful in rigorous arguments, but how fun is to converse with someone who throws that around after every sentence?

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.
