I do not believe that personal attacks have a place on JoeUser. I feel that it is detrimental for the service of everyone if people cannot work past their differences, or take it elsewhere, assuming that the other party agrees. I have a place to go to attack me, so it's not necessary to ruin other people's days by making them read attacks here. If they care, they can go there.
When you attack somebody on JU, not only do you violate the Terms of Service (which you did read, didn't you?), you also detract from everyone's experience. Not only that, but it opens up a whole can of worms. You look as stupid as whoever you're attacking (if you succeed, if not, then you look more stupid). Not only that, but it's like smoking, then extingushing your cigarette butt on somebody's doorframe. It's just plain disrespectful and messy. And they're your host, too.
So, quite frankly, take it outside.
