Hi Tashdid, it is meant to be ironic. ;)

Trump and his followers might think that Trump has no blind spots, whilst reasonable people, people who are not idolizing Trump, accept that none of us, not Trump, not even Obama, are perfect. Based on this commonly accepted view of humans, Trump, and his followers appear to be a a bit silly (or maybe exceptional in their own eyes) ☺

So yes, you are absolutely right. Trump is maybe the personification of the blind spot.

Our blind spot is that we don’t see that half of us prefer a man with tunnel vision to a person with a more open and reasonable perspective, to represent us.
