As soon as you know someone is "ex-communicated" from society you must go out of your way to never ever possibly see or interact with them forever for life?
Get real. I'm not turning around to go home every time I see an "ex-communicated" individual.
Who keeps track of this list of individuals, where do I go to get an updated list so I can immediately vacate when one arrives? What happens if someone is added to the list after I have met them?? Am I on the list by association??
This is bonkers.
I believe that the list of individuals is available online in real time, it's called the sex offender registry.
The basic idea is that we do expect some degree of moral responsibility from our leaders, elected or otherwise. Most of them absolutely operate with and require some public support.
People are just setting a higher bar for what that support requires.
The litmus test for what HN suppresses is in which topics one side (but it's only ever one) can talk like this without a stern talking to or threat of bans.
