Dorinda has had nasty moments since her first season. She went off on Heather out of the blue her first season. She set her sights on Sonja and that went on for a couple seasons. She only decided to become Sonja’s champion this year to cause a rift between Sonja and Ramona. She then went after Luanne and that was nasty. Finally, the attack on Tinsley. Tinsley didn’t do shit to Dorinda; of course Heather, Sonja, and Luanne didn’t either. She has always used Richard’s death as her “out” for her behavior. I don’t buy that her behavior is entirely linked to his death. The man died of liver failure. I think alcohol has played a role in Dorinda’s life for some time. None of the other ladies would bring that up, but honestly I don’t think Dorinda would’ve extended the same courtesy to any of them.
A few other housewives from other shows have been pretty nasty...Tamara, Nene, Vicki, Rinna, Brandi, Leanne, etc... but I’m hard pressed to find one as unapologetically nasty as Dorinda (maybe Rinna or Brandi).
