In my opinion, people get offended too easily. On a competitive platform of online interaction there will always be one calling someone else an offensive remark. That can take the form of personal insults, family insults (living or dead), unborn children, nation of origin, racial origin, personal development of the said character (lesser intelligence, physique, intimate parts, etc).
I`m not saying this should be accepted as the norm, but i am saying that people should not be offended by someone who wants to spite you, anger you, trigger you in any way, or just has a mean attitude and is enjoying your torment. Think of this as a growing opportunity. In real life you`ll always be faced with these challenges. Instead of getting offended or angry about it, try to develop a neutral attitude here on this server first, and then apply them in real life. Be more mature then the person who directs them. You be the better party and leave him in his lowly pit to marinate. Don`t get caught up or dragged down to their level, by responding in kind, because you won`t be any better.
We have to accept that we each have a certain level of development, both mentally and spiritually. Just let them be.
