Nah hard disagree. Extend politeness until they give you a reason not to. Then it’s fair game.
Discussion
Morality is for your friends not your enemies. Make a filter for sorting the people you meet. Politeness used to be as simple filter applied to newly met individuals. Got conflated with morality and thus the filter broke. Many such cases.
You get it
I believe we’re saying the same thing 👍🏻
Being polite as a filter for who your friends are is broken. People(enemies) will use your politeness as a cudgel against you. I am saying you are running outdated software and might need to patch some parameters surrounding with whom you are being polite. An exploit has been found and running that older code leaves you vulnerable.
