Don asked "So why the decline?"
Mark responded "I am glad you asked. They turned away from rationality, embraced fundamentalism and science became heresy."
DonDiego understands this response. If, indeed, that is the cause of the decline it is most unfortunate.
DonDiego opines the rest of Mark's response is an excessive and unfair characterization of that portion of the US population which elected President Trump.
[Poor old DonDiego voted for Mr. Trump, . . . first and foremost because he opined Ms. Clinton to be the more despicable of the two foremost candidates. And at the time poor old DonDiego was not even aware of the existence of Hillary's sex dungeon in a pizzeria !]
In fact DonDiego does not hold any of the "beliefs" which Mark ascribes to those who support President Trump. But, . . . he does opine that a wall would aid in securing the border; he has found the healthcare available to him in the USA has been quite adequate; he supports the 2nd Amendment "right to bear arms". [He also recognizes the ability to amend the Constitution to eliminate this provision, if sufficient support to do so exists. Those Founding Fathers were really something !]
In spite of these opinions he hasn't ascribed "Christ-like" attributes to any politician, . . . and is unlikely to do so in the future.
Unsubstantiated diatribes against and mischaracterizations of those with whom one disagrees are seldom productive.
