They're just words and only you can let them effect or hurt you. Just ignore anything you deem offensive.
I don't think most of those words ate just words like you said, because everyone has their own right despite the rank the one may be, is not right for some users to abuse others on the forum because it hurts more than punishment, some users brings their real characters into this forum to intimate others, it is beter to give advice than to use offensive words on another, everyone is here to fetch knowledge and not the other way round.
