Most people believe, more or less, that the value of a human life is the same, irrespective of where on the planet it happens to find itself. But, of course, not every life has the same value for us.

I just think that the skepticism about truth has almost completely flipped - from being something associated with generally left-leaning progressives to being something which is a tool of right-wing populists and demagogues.
