I am rather concerned about the recent willingness of some HN commenters to jettison basic practices of civilised discourse when it even remotely involves the Russian-Ukrainian conflict. If one has a convincing argument, one should just make it. There is nothing pedantic about that. Insinuating derangement and denying common sense should not be necessary. Those who feel they have to resort to such practices usually do so precisely because they are unable to make a convincing argument. Why else would one act like this?
