Will probably regret sticking an oar in, but here is my humble opinion on the lies/bullshit/shades of truthiness thingy:

I want to see the word ‘lie’ used loudly and often.
Not because it describes how Trump sees/understands the truth or otherwise of what he’s saying — that will still be getting argued in the history books. But because words matter in how people see him NOW.

I just want consistent, persistent messaging to be engrained in the public consciousness by repetition. Trump = lie. Trump = liar. Trump = false. Trump = take with a bucket of salt. ‘THIS’ is a fact but Trump says ‘that’ — preferably in that order, so that the true statement comes first. If Trump says it, don’t believe it.
Like dripping water, carving out a defined channel in the listener’s mind — the words Trump/lie immediately linked.
And if we can expand that to the GOP in general, all the better. GOP = Trump = lie.
