General word of advice.

[Marti]

Sorry, man -- I know it might not be the ideal answer, but this is pretty much the way of the internet. For the most part, you don't have a right and guarantee not to be offended online. By the very nature of the internet you should expect people to be insulting, and should also keep in mind that it has little resemblance to how they would treat you in real life. If you really can't deal with it, there are plenty of places online that will protect you, but I honestly can't understand how people take it so personally that they die over it.
