As far as Danielle setting a good example for her daughters I don't think the poster was talking about the negative behaviors that must be demonstrated to win this game.
He was referring to her willingness to use her brain and not her sex appeal to get ahead. This is a quality Danielle probably possesses in her everyday life which is a good example for her daughters.
Danielle comes across to me as strong stable woman who is probably a good caretaker of her family.
Saying she is not a good role model for her kids based on gameplay is like saying football and hockey players are abusive parents because the sport they play is violent.
I agree with the original poster that it is great to see a woman who thinks and strategizes versus a woman who uses her feminine wiles or sex appeal to further herself.
