What I got from that thread is a reminder that everyone is a judgy prick who likes to jump to conclusions.
You have no clue the context other people are in.
This is no different than the realization that the person you are road raging at might be on their way to the hospital.
If you do know the person and they do have a problem, public shaming them isn't doing anything productive anyway. Maybe look for a way to help instead of just judging and shaming others.
Live your life right and leave it at that. Your obsession with forcing strangers to live like you is just you being an authoritarian prick.
