Okay
Stop for forcing people to NOT be them selfs.
You are actually being rude to themselves.
This is the reason why people don't like you.
You are forcing to do people something that YOU desire. It's not your choice how people will act.
You are not in an upper position to talk down to someone.
Are they saying to you "Be rude"?
No
Do you in the other way?
Yes
I hope you understand now and that you taken something from this.
Stop Larping as someone that it's NOT you, we both know that.
If everybody would "be nice" there would be no nice.
No one would appreciate niceness.
It will be common and word will be boring.
