I love engaging with pedants like that. It infuriates them as I agree with all their overly-narrow points but then show how they don't support their conclusion. They don't really know what to do so they just keep reiterating the same irrelevant points over and over in slightly different ways. Sometimes the back and forth would go on for days when I was on reddit.
It's my way of having fun and paying penance for my past pedantry at the same time.
