Apropos a recent spat, I wonder what the opinions are on the threshold percentage for what qualifies as a "vast majority"?
I haven't seen this argument.
So, what do we think a "vast majority" is? I propose ≥︎ 99%, but I suppose I might be prepared to go as low as ≥︎ 95%.
Vast majority - in most cases I'd agree with you, it's over-used by feeble minded politicians. One of my most hated expressions is "the vast majority of the British people". Noone has every surveyed me, or anyone I know, so how can you make such an assertion?
As for absolute, simple, large, significant, huge, overwhelming etc., all rather meaningless (even "majority", maybe)
Context is everything. You might say Labour had a large majority at the election. Seats maybe, percentage of votes cast or even percentage of votes that
could have been cast, I don't think so. In fact, no majority at all (20.1% of those eligible to vote).
If we must put a figure on vast majority, and in the 90%+ area sounds good, we'd need to insist that all those eligible are counted - as in your definition of absolute majority. But as politicians won't, then any prefix to majority could/should be treated with scepticism.
