It's fairly well known here what I think of Trump, so no need to speak of that.
However, regarding the Rally and the Protest last night in Chicago, let me say that while I agree fully that both sides have the Constitutional right to assemble and express their beliefs/speech.
What is not acceptable is when one side (with whatever measure) silences the other side. Regardless of which side it is, this is not Constitutional.
Neither side is innocent in all of this, for there are documented instances of violence initiated by members of both sides.
In my opinion, a large part of the blame for such things lies with the Authorities. There is NO WAY they did not know such a protest was planned, and they did not properly prepare for what transpired.
All they had to do was establish "zones" for both sides to assemble in, and anyone (from either side) that violated their designated "zone" should have been arrested.
When the Constitutional right to protest turns into an attempt to silence those opposed to ones beliefs, it is no longer a Constitutional (1st Amendment right), it is Domestic Terrorism.
Blame is plentiful, and even Trump (given his rhetoric) shares in the blame for such as occurred in Chicago.
