Don't get the wrong idea from what arun said... I'm pretty sure he didn't mean it wasn't your fault for some parts.
You flame, and you get involved, therefore you are at fault on those times. The only time you wouldn't be at fault would be if you didn't flame at all and you let people flame you... But you were involved. You all sink and swim.
I personally believe you were not flame baited. No one wanted to start a fight. None of the minions here are like that from what I know. They were not all up your ass to get you demoted. You could have handled replies in a non-flamy response, but as you let loose and started flaming then that's where the shitstorm began. It's something you can't go back on now. What's been done has been done, and you've admitted to your mistakes. Alright. It's good you realize what you've done wrong. But I hope you know that it isn't going to guaruntee the chance, as most people in staff are very upset. So yea, gl again.
