Re: Nope, the truth is not relative
There are big Grey Areas.
Any campaigning politician will maintain levels of ambiguity and plausible deniability on many matters likely to be controversial. Sometimes rightly so, like when being pressed to answer a "Have you stopped beating your wife" question. Did you notice in the recent campaign, the Tory campaign centred on (things they said about) Corbyn? That appears to have backfired: it was just too blatant, but if Corbyn had risen to the bait and spent his time denying things that were (often-misleading spin) but not outright lies, he'd've been crushed by it.
Or consider the "Melanie Phillips translation": you take something said in a foreign language and translate it into something monstrous in English.
I could go on. But not here.
