Actually what Trump has done is give those who read leftist journalism a reason to question the validity of said journalists.  The most recent few weeks has shown the amount of "spin" the liberal media takes on anything Trump.  From blasting his preference of golf courses to the first lady's feigned 'hand slap', MSM has shown contempt for even the most inconsequential, unimportant occurrences seeking to 'throw shade' on everything Trump, true or not.  As I indicated to another commenter the MSM has admitted to Trump stories being 89-91% negative.  Knowing this I think the media has more responsibility for reactionary outbursts than the individuals.  It is liberal media that has created the monster not Trump.  Trump has merely exposed it.
