No, it’s perfectly rational, because having poor grammar is bayesian evidence that they’re stupid. There are other explanations, such as speaking a different first language, but they are less likely. I recall one instance in which I assumed that someone who had poor grammar over the internet was speaking a second language, but later found out that he was literally brain damaged. mormon1 could be speaking English as his second language, but it is much more likely that he’s just an idiot, in which case reading his posts is a waste of time and thinking about them is a waste of reason.
