They are each 100% to blame for any coming accident.
If a man cheats on his wife he is to blame 100%. If a women withholds sex from her husband, she may not be 100% to blame. But she has blame. Her blame does not diminish his. Its her blame.
The flaw in this reasoning is the hidden assumption that each happens in a vaccuum. They don't. Each affects the other. If a man is getting his needs met sexually, emotionally, and psychologically, he is far less likely to stray. Women who withhold from their husbands are not doing them any favors, they are actually mistreating them. Actions have consequences, and what we do affects those around us. You cannot ignore the interaction of actions, and the resulting consequences. Dr. Laura is correct in her assessment, if you take the time to think about what she did, and didn't say. Too many here have posted knee-jerk reactions, which show that they didn't really understand what she said, nor did they think about it.
Do I think Spitzer should resign? Yes, Immediately. It's about time that some Democrats show that they actually have a conscience and morals, instead of giving Spitzer a pass on this. When Republicans are caught in moral failings, they do the right thing and resign. Democrats don't, unless they are forced. It's time to force Spitzer to pay the piper, and resign from office. I hope his wife dumps him, too. It would be the right thing to do.
