Dear Two,
It is so easy to understand, that it does not have to be continually stated. Trump hates the KKK. But his critics claim he does not in far enough to condemn the group. The only reason Trump is accursed of supporting far right groups, is because he sounds like them. Once his position is known, it is stupid to keep asking him to condemn them. In short, condemning violence to clarify policy is pointless.
You made a different point. That the current trend is so abnormal, that it must be condemned. First, we would have to check the record of who condemned it. Once is enough. Those that harp on it are doing it for political gain. (Which is perfectly legitimate.)
At this point, the protests and riots, have lost their momentum. The agenda-driven activists, have returned to their regular activities. It is clear that the violence is more about a lack of faith in law and order, or truth and justice. The solution is to confront the violence and shut it down. At this time, words ring hollow.
