There is a difference between a president spreading lies so that half of the population believes them (such as the election fraud lie that has been disproven in court, repeatedly), and a few people in the population (that is, regular people, not the president) rioting for real or perceived injustices. Almost all republicans believe his lies, but almost no democrats are rioting or protesting. If a black kid in Baltimore robs a store in a BLM shirt, this doesn't have any reflection on me as a democrat in my state. But if an entire subset of America falls for the constant distribution of lies from the head of the country, it's a little bit more serious, don't you think?
