More accurately, synonymous with recent US Presidential debate.
Civil debate, people take turns and listen to each other; Anecdoche. everybody talks at once, nobody listens.
I've been a reader | writer | speaker of commonwealth English for decades, this has the feel of a list of words less familiar to American English speakers; there are a few words I've not come across - most might feature in an episode of Have I Got News for You (panel programm that rips and riffs on contemporary UK news events) or other chatty talkfests.
I dunno, I'd rather start with words that are rare but that other people will know; if nobody understands you, how useful can they be? (Edit: In fairness, an unknown word could have value, but it feels like pushing the line between being clever and egotistical)
There are some very useful words in this list, but I kinda wish they were ordered by some metric for usefulness rather than alfabetically.
I guess ordering them by popularity would kinda defeat the purpose though...
