I've been pinged back to this thread today because of the ongoing issues with FoxNews bias against Trump.
RE your long prescription for what Trump shoulda said, what he said was, "Frankly, I don't have time for Political Correctness and neither do the American people..." at which the audience broken into loud, raucous applause. In that one short sentence, he summed up everything else your post was about, with a great economy of words. His campaign has run the same way: on time and under budget, like many of his building projects, because of his skillful use of social media and weaponized sound bites. The man is so much smarter than he is given credit for.
Trump did not use his entertainment and his business credential to talk down to an “objective moderator.” If he had done so he would not have merely gotten huge applause, he would have started a demonstration in the aisles similar to what’s seen in political conventions. He would have proved that Kelly did not know her audience and Trump did. Kelly would have lost control of the situation.
