San Francisco Giants and Dallas Cowboys since the day I was born. Also became a Baltimore Ravens fan in 2000 (before they won the Super Bowl) and still love them. Became an Oklahoma City Thunder fan when they first moved there as my family is largely Okies aside from myself.
You don't abandon your team because they're sucking.
Of course, one should never be a RAIDERS fan in the first place. Awful, awful franchise. Awful city, awful fans. Just awful all around.
PLUS YOUR EX WAS A RAIDERS FAN OMG THANKS FOR SHARING THAT EMOTIONAL STORY!!! I FEEL SO BAD FOR YOU!
