If you had an IQ, you would know that Trumps rhetoric is intended to trigger dishonest, low IQ morons who voted for an idiot like Biden.
If you had an IQ, you would know that Biden is what morons on the left claim about Trump. But alas, Biden voters are the definition of moron and are A OK with authoritarianism and Marxist ideologues as long as they have a "D" next to their name.
