Should we be held accountable for what we say online?

I do not think it is in any way necessary to punish people for saying things online unless they are hackers, or make some sort of life altering threat. If people argue on myspace, facebook, or twitter, it is usually pointless, mindless arguing. It is the same thing as people arguing over the telephone, or getting into it over something as simple as a person skipping you in line. I have said it before this blog and will say it again, IT IS JUST MYSPACE. It's not like some one is knocking on your door and threatening you or stalking you. Although like I mentioned if they are truly threatening you than they probably should be held accountable for their words.
