OK, things like truth and fact and their antithesis are relative to individual perspectives. So, lets abolish all those institutions that depend on truth and fact not being relative starting with the recent Presidential election. Trump didn't win, nor did Clinton lose, etc.
Personally, I prefer a world where "evidence" determines the difference between fact and fiction, truth and lies. I believe, sooner or later (better the former) Trump and his supporters will find that kind of world more convenient.  Nasty brutish things start to happen when people grow frustrated with too much of other people's point of view. And what's to stop that happening in a world where everything is relative? Where does "We hold these truths to be self-evident" fit in a world where everything is relative?
