Certainly we should be striving for objectivity. But our political divisions run deep, and many people have a hard time seeing the other side's point of view. Your assertion that "[i]n Trump's world objectivity is not a goal" is indicative that you aren't open to the possibility that he's being more objective than you think, therefore, if your view is less objective than you think, then clearly you're part of the problem. Of course, maybe you're right, but you don't seem open to the possibility that you're wrong. And that simply illustrates my point about the difficulty of arriving at objective truth in matters where we're so deeply divided.
