While it easy to think of vengeance, I think it raises an important question about how to identify and manage the dangerously insane, which Matthew Taylor Coleman clearly is. QAnon has to my mind crossed the line from freedom of speech to peddling hatred and lunacy, and as such needs to be shut down. I realise that this would be difficult as roughly half the Republican Party also peddles hatred and lunacy - just look at Marjorie Taylor Greene, for example.

I have no easy solutions to this problem, and it may be that there are no easy solutions.
