We've deprived a whole generation of the rhetorical tools for healthy, impersonal and professional argument. It's no wonder that they've pressed this "stylized language of emotion and abuse" into service to fill the void: it's all they know.
The lack of emotional (and explicitly confrontational) experiences in modern society are underdeveloping skills to deal with them.
Consequently, you get childish spats over what should be a technical disagreement, because people aren't comfortable saying "I think you're wrong, but I respect your opinion. Here are the reasons I think you're wrong..."
As the quip goes, anonymity and the lack of physical presence turns everyone into an asshole on the internet -- and then we raised most of the world on the internet.
1. English is a Germanic language, not a Romance one.
2. Even for speakers of Romance languages, knowledge of the ancestor language doesn't really make a difference. Does it help a modern English speaker to know that silly once meant "blessed by God"?
3. The notion that Latin is somehow more logical than English is a pervasive one, but it has absolutely no evidentiary underpinning. It's pure classist bullshit.
As a result of the current geopolitics, we don't have the self-awareness to realize that minor conflicts are minor conflicts and that the absolute best place to be and thing to be doing is spending time at home with your loved ones.
We certainly shouldn't be carrying out PR strategy wars against our colleagues like is happening here...
