Stripped bare, Trump sidesteps having to argue his position by using common rhetorical devices instead. While persuasive (after all, he has millions of supporters), these arguments tend to be without substance and well ... bad. See, not all arguments are created equal. In fact, some arguments are just plain bad. They use logical fallacies (flaws in thinking) to make a point that may not be true. And that's all the more reason to learn to identify them when you see them.
