I’m not sure I get the question. Are you suggesting there’s been a recent escalation over time in the melodrama of the words we choose?
If so, it’s certainly not something that I’ve noticed. If anything, I’d suggest that our word selection, overall, has gotten softer over recent years.
Check out last week’s On Language column from the NYT Magazine regarding increased abuse of the conditional as a method of expressing humility.
“What bugs me, however, is the growing abuse of the conditional mood. ‘I would hope that we can finish the bill next week,’ said the Senate majority leader, Harry Reid. At the same time, Vice President Dick Cheney was saying, ‘I would hope that it’d be one of the issues in this campaign.’ Why the wishy-washy would hope? If what event did not intervene? Why not a straightforward ‘I hope we can’ and ‘I hope it will be,’ unencumbered by the moody modifier?”
Obviously this article is specifically about politicians’ use of language, so noticing trends like this really depends on the sort of people you run with.
