Why does everything turn into an arguement????

As long as I have been on the net I have never understood this myself. Who gives a crap if you don't have noting good to say and think it is stupid are what ever it is with you and a mans post then just move on . Its just as easy to click on something else than to post some kinda crap that you know is gonna get in the next mans crawl I imagine that is why some do it . I see a ton of stuff on these boards that I think unreal man just unreal but I don't go to say hey man your full of it are your crazy as hell and a fool a liar and everything else . Its crazy man you know it is gonna start a augment so why the hell post it unless that is what you was looking for in the first place and am sure there is a ton of that going on to.
