Hello Turgid Member,
Indeed it's easy enough to ignore, But it sure does let people show who they are.
I believe that is the best course of action. Here's why:
It should be realized that a chat room is not representative of society in general.
It makes sense that people who are anti-social in real life can find a way to interact with others on the internet.
So online chat rooms tend to collect more of these people than are encountered in real life.
If these individuals are so abrasive that few wish to have anything to do with them IRL, they will find a way to interact with others online.
The problem is, if they do not know how to have a friendly functional two-way conversation, and simply lack the ability to restrain themselves from nasty outbursts, they resign themselves to being dysfunctional online conversationalists, IOW, they become trolls.
They lack the ability to have civil discourse and find that it is easy to get a response, (any response will do,) by insulting people. And they are reduced to nothing more than such pathetic appeals for attention because they do not know how to conduct a mutually respectful dialog with another individual with which they may disagree politically. They are stricken with unresolved anger. They attempt to rid themselves of this anger by unloading their frustration on others. But they find that any resultant endorphin rush found in 'telling someone off' online is short-lived, and does not resolve their anger. Thus, the action must be repeated.
They then find that they fall into a habit of provoking others and getting the response of the annoyed other. If they find another individual who is prone to fall into the trap of attempting to silence the troll, a dysfunctional exchange is initiated in which each individual attempts to 'have the last word.'
When people have a habit of online nasty talk, they become desensitized to it, believe it is commonplace among everyone, regardless of the fact that it is not.
Also, it is logical that online habits are carried into real life situations. If an individual has an online habit of nasty talk, it becomes rather challenging to prevent that from seeping into real life. That would usually occur when the individual is under the influence of strong emotion. It is then that is is most difficult to remain mature and in control.
That being the likely situation, the best course of action for personal peace of mind is to avoid allowing oneself to devolve into online trolling or nasty exchanges with online trolls.
