He isn’t wishing death on anyone. He’s simply pointing out a list of people who are so unhinged that they openly wish death upon others with opposing political views. Those kinds of people are dangerous, and I want to know whether I’m associated with them or not.
If something bad were to happen to any of these individuals, the responsibility would lie solely with the person who committed the act, not with those who called out their behavior.
Calling out toxic behavior and toxic people does not make them a target. By that logic, no one should ever be held accountable for anything, because “maybe one unstable person might react violently.” That reasoning makes no sense at all to me.
