I don't know any of the people involved in this, but from an outside perspective it sort of looks like this.

Kicked user posts 10 pages of rant and doesn't know how to edit over 200 char even after being told.
Says hes ok with it, but continues to vent.

Accused FC has a very classy post wishing him luck and not really bringing up what happened.

Gonna be honest bro you sound like you might be the problem, and you are blaming other people/this FC.
Obviously in the scenario you described about missing a raid date, they would be jerks for kicking you.
But as we all know thats just the scenario you described and probably left out a whole bunch of stuff that was the real reason for you being kicked.
You probably don't even know what you did, because you can't see your own problems. Might be time to look in the mirror. And maybe you are a horrible person like the LS said you were.
