One thing is for sure, it's a coward because if you have to be anonymous to talk shit all the time, that says a lot about what kind of person you are.
Depends on what you consider "shit". A lot of people here talk truth, which is considered "shit" by the people like you who can't handle the truth.
Who is the coward? The guy who wants to fight someone for talking truth or the guy who talks truth under a different name?
Coward is just a word bandied around by people like you who don't like to be disagreed with. That, to me is another form of cowardice.
(In no way am I debating the actual comments about dzulboy as I have no idea what was said)
