" I wonder how much love Trump would get if he stood up at one of his famous rallies and lectured his audience on anti-Semitism." Would not make any difference. Do you think the people there are ideologists of any kind? Most probably don't even know what is anti-semitism. The people are there as reality TV fans coming to see one of their stars, and of course for a free coffee and a stupid cap. The fascists backing Trump do not meddle with this crowd.
