People seem to rally around those who use name-calling as their primary response to something.
We must try to put into words what we need to communicate without name-calling or the message is lost in a petty insult.
People also seem to rally around those who promote brash action.
We must try to find non-destructive solutions first before opting for the easier option of destroying something or the progress is lost in a tantrum.
People seem to rally around such people who accuse others of what they do.
We must look at our actions and the actions of the accused to see if there is any difference or the problem is perpetuated but merely by different people.
If someone is unable to avoid petty insults, brash actions, and hypocritical accusations when communicating, that person needs to stop and think about what's really wrong and deal with that, and others need to stop and reconsider everything that the person said and did from a vacuum existing only of that one person -- nobody else, just that one person's words and actions alone -- replace everyone else in the conversation with a blank.
To be mature is simply one thing: Don't be petty.
There is far too much pettiness around from everywhere and far too much acceptance of it if it's from someone we trust.
EDIT: Interesting: A post about not being petty received a -1 and no comment.
