I'm glad I read all of your guys posts, saved me a lot of typing
Maybe the similarities between the illegal alien shooter and the Dude is what rubs him the wrong way?
Dude has been "deported" what, 4 or 5 or more times? Only to "sneak back across the border", play nice for awhile, then reveal himself and try to convince others he's a changed man. It doesn't take long for him to go back to the same behavior that got him 86'ed in the first place. He's trying to force others to accept him instead of fixing his behavior.
As redsox said, dude always has a "one up" story. Just a little better, a little more dramatic, or a little more pitiful that someone else. It really starts to reek of attention whore.
If he actually had a rough life, crappy childhood, or whatever, It's up to him to figure out how to deal with it. The world doesn't owe anybody anything for how their life has evolved. I'll preface this next comment with this: It's a generalization and not necessarily directed at The Dude. I'm not making accusations or assuming anything when I say: Whether it's bad parenting, poor life choices, or someone just got the sh!tty end of the stick in life, it's no one else's fault, and others can only do so much to help fix it. The majority of the weight of fixing a shitty situation falls on the shoulders of the individual involved.
When others do try to help and the behavior doesn't change.............
Lastly, his behavior isn't unique to 3WW. He has a reputation for the same type of behavior on other websites.
You ladies have a nice day! (Yea, you too Dude) I'm heading outside shortly, this weather ain't gonna last much longer.
