Are you surprised? The psudo-conservative and Christian right has been celebrating in their homes, to and with each other and in online message boards like this one since the leaking (an extraordinary Supreme Court event in its own right) of the opinion. What else would you expect, both sides having a tendency to count their chickens before they are hatched. No. You are not surprised, any more than I am, or most of the people on this board, regardless of position.
Good last paragraph. I had not thought about that, I guess because the event is still so new. We've seen what excess and violence the radical right will do when it is deeply disappointed. There is no shortage of radical violently inclined or willingly led on the left. Of course, the Trumpists had a dubious leader to encourage and act as a catalyst for their rage. I cannot imagine who, the radical left would listen to, with the same immoral authority to direct and spark the event. Still, I was one of those that just did not believe the trumpists would do such a thing and was totally wrong. So, I hope somebody at the correct level is considering your same thoughts of possible violence and taking appropriate protective measures.
