It's an unfortunate thing we need to come to terms with, but rape is one of the hardest things to prove in the court of law. Hillary went to relatively extensive measures in order to attempt to prove the defendant was innocent, because she was very much fighting an up-hill battle if she knew the defendant was guilty. And I wouldn't call what she said "personal attacks", more so fabrications to create a stronger case; I don't know whether the comments made by Hillary about the victim were accepted as truth at the time or not.
I do find it ridiculous that because she argued against a female rape victim, she must be contradicting herself when she's supportive of women's rights, but then again, in our modern, first-world society, women's rights are basically equal to men, so the initial statement is ridiculous anyhow. Feminists need to fight the battles in Saudi Arabia and the like instead of stomping around, looking for any indication of inequality and calling anything they choose out in countries like the US and UK.
