The purpose of the website is not necessarily chastise soap operas but to point out these stereotypes and make people more aware of their existance and thier ridiculousness. These stereotypes are not just typical of soap operas.
Hank is the prestigious district attorney.
He probably had it just as rough as R.J. growing up but he was the kid who got out of the rut and managed to make something of his life. For one, Hank is older and I believe his character was introduced as a successful lawyer from the start. He was never portrayed as a young black male. Hank is thrown in there to be that black male that the viewers of the show may somehow know and would not dare to offend by calling him a natural criminal. The reason for his high status is because very few people on soap operas have low statuses.
