According to loyceV “If you can be offended by someone online, it means you’re doing something wrong”.
I actually don’t see any need why the forum should start censoring post just because they included a curse word in it, if you don’t like the way an user responded to your post the best thing you can do is to ignore them and forget something ever happened rather than to start engaging in a heated argument with both of you insulting yourself, after all you don’t know them and they don’t know you, so don’t let anyone’s words get to your head.
Don’t forget that this is a forum and everyone should be able to give his or her own opinion without being censored. And once the content of user get removed because of their choice of words then that would defeat the whole idea of “freedom of speech”.
Some people practice such rush behavior that they easily get offended and attack others with bad words. I do not think there is anything we can do about it. Sometimes a word serves different meanings depending on which region of the globe that word is being used. One community slung can be one community's general expression. If the moderator starts censoring every foul word they they won't get the time to do other important work.
