You entirely missed the point to why Spartan was banned, it wasn't because he put forward his opinion, it's because he did it in a disrespectful and offensive way. Plus, there were many other things that contributed to his banning, this was the last straw basically.
As said ALREADY, if you want to discuss it further, start a topic in the War Zone for it. If not, then stop bringing it up, this topic is not about him. I would have thought you of all people would understand were I was coming from with the banning Chrisman.
As for your post, I know what you mean, chances are he was bullied, probably a racism victim. He may have been asking for help for some time, but nobody cared (that doesn't include mental help, I'm talking help to stop the bullying, harassment, racism, etc.). However, taking that into consideration, I think don't believe for one second that going and killing 32 people was a good way to go about it, no matter how hard it gets harming yourself and/or others is not right.
I heard he didn't loose a girlfriend, I heard he was after a girl, and she said no to him. I also heard he became a stalker, stalking girls around the school. This is from the news, so it may or may not be 100% correct.
