Donald Trump's schtick is that of a fear-mongering manipulator who makes hyperbolic appeals to the xenophobic nature and white resentment of his uneducated base of support. His base swallows it whole every time. This forum is a microcosm of that.
Trump knows that his base of support is ignorant, and he exploits that. You blindly trust that everything he says is genuine, and you are not intelligent enough to think for yourselves, and realize when you are being manipulated by someone with a self-serving political agenda.
Donald Trump's political fortunes hinge entirely upon his success at promoting division.
