I love your optimism, as it should be. Unfortunately the law of the universe is against you — bummer. Trump will not only have the power to hurt you, he will have the power to liquidate all of humanity and most higher forms of life on earth with just one impetuous wrong move.
Meanwhile he has limited powers to undercut all the regulations that helped to curtail those looking for short-term gains that poison us all.
We need to build a wall. We need to build a wall around Trump to protect the good and rational folks from his devilish antics.
