So considerate of someone you don't want posting to you ever again.
It’s called courtesy. I try to treat others as I like to be treated. It takes a lot of effort but I make an extra effort if I expect them not to have the same manners.
If I am only kind to people who act as I wish what is the value? If I can show everyone the same courtesy I hope that each individual notices it. It may lead to a common ground for understanding in disagreements.
Is my behavior really so bizarre? Sad world we live in, isn’t it?
Anyways, it’s too damned easy to be rude and insulting. I try to leave that for lesser people to enjoy. Sometimes I'm even successful.
