Drunk Leagueing :: Death Sentence??

Hey guys, So recently I was permabanned for bad behavior during a game or two I played while I was inebriated. I wont say that justifies my behavior, but I think a permanent ban might be too harsh for my first ban ever. People can get off with probation for killing people while drunk driving but extremely rude behavior for a couple games can get you permanently banned?? Obviously, this comparison is extreme but I would like a less harsh sentence for one of my few offenses (and only punishable one) especially after sinking so much time and money in the game. If not, that is okay, I can accept the consequences and start over if I have to. Thanks for taking the time to read this.
