Most offenses are nothing more than trolling. People understand you don't feed the trolls. If you are offended, then you were played.
In these situations, responding only results in more attacks (trolling). It derails you from the important things in your life. If you responded to every poke in the eye on social media, it would consume you.
When necessary, defend your honor with truth and logic, but avoid being offended. As that is the path down to irrational tantrum.
