How do you know for sure that his mama will be portrayed in a stereotypical way? As to Shelton being "a former college wrestling standout with great prowrestling ability that is hungry for the title" you know that that is not considered enough in the WWE. You can not like it and complain about it, but that's how Vince, Steph and others see things.
Dude, seriously, considering I have a lot of 50+ something black, heavy set, good personality women in my family, I think i can safely say that this woman will be stereotyped a certain way...what do you think she's going to do, just stand there and cheer him on?
