Perhaps the point isn't about arguing about something trivial that impacts no one, but about when one is arguing against dangerous ideologies for which the objectives transform things into zero-sum games; e.g. arguing against fascism (because power will be stripped against the many, and put in the hands of a few authoritarians), or against anti-feminism. The world is filled with people that have taken the bait ("pilled") and that don't realize they're (or are actively) enabling this concentration of power while they're focused on hating a small demographic (LGBTQ, feminists, black people, immigrants).

I don't think we've solved the problem of what to do with evil people that are too smart to pretend they have been rehabilitated. So, an amicable chat with them won't really win them over.
