There are people who I really do not like and there are people out there who do not like me. It is a fact of life. And guess what: There are people who for whatever inconceivable reason do like that person I do not like. Yes, even love them. And these people who do not like me: Some cannot tell to their friends what exactly the problem with me is but they do not like me. Bad luck.
But now I have a solid reason for my dislike: XYZ is X-ist ! Whatever it is, it is really, really bad. Every human who is not X-ist must recognize that.
Now how do I handle the situation ?
I can say that I find his/her behavior not ok. In public or in private. XYZ knows now what I think and he/she can think over it.
Perhaps he/she is sorry. Everyone could make mistakes. I can accept that or not.
Perhaps he/she is aggressive. Then I could block him/her.
Whatever he/she thinks or does, the community have only a marginal influence on what XYZ really thinks. But what the community could do is not tolerating behavior which violates the rules of the community. And that is ok. If XYZ continues intolerable behavior, he will be punished.
The important thing about the community rules are that they should be fair. They should not be invoked because you have the wrong race, religion, sex or whatever, they are invoked because rules have been broken.
But I can also think that what the person did is inexcusable, and therefore I try to use the community for my own personal vendetta. That means I do not use chat for talking or conversing or solving conflicts, but to stir up the confrontation in the hope to get backup for punishing XYZ without community rules.
And that is not what the intention of the chat is. It is NOT intended to raise conflict. It is NOT intended to draw in the community in a personal conflict. Guess what ? People can read. They know the conflict and are NOT interested.
REALLY ABSOLUTELY NOT INTERESTED !
Stirring up confrontation is violating the rules, too.
Is that understandable ?
