How does "official" status (which is in any case not required for the verb "eulogize") have any relevance to whether it's appropriate to challenge people in a context where they can't respond to that challenge without breaking social obligations? If I say "Emacs is without a doubt the best editor", then I naturally expect Vi fans to defend their favorite editor. There is in fact doubt, and they can surely come up with reasons why Vi could be considered better. But if I make my claim when any defense of Vi would be downvoted for distracting from more important issues then I am not arguing in good faith.
