In the Oakland/ San fran area is it ok to root for both Raiders and 49ers?

1 you cant root for the raiders if your white thats only for Mexican's and black people #2 no you can not be a fan of both its against the rules. #3 being a fan of the raiders is like being a fan of the clippers its just a waste of time because they will just trade their best player for money anyway. #4 Al Davis is a bad owner just ask Marcus Allen he flipped him off in the end zone because Al Davis would not trade him or give him a raise after one of his best years ever.
