The biggest issue with the Weinstein story is that she described something that clearly wasnt his modus operandi (and yes, she has changed many details between every interview and column), combined with her general tendency to lie and to jump on every bandwagon you cannot blame anyone for not believing her.
It's also...even if it was true....her taunting messages to Ioan about dating rich executives and making it that way in Hollywood shows how ungenuine she was about the Weinstein story, as well as what NarcRage pointed out wrt victim blaming his real victims. If Alice wouldnt have been a genuinely good looking woman back in the day I would have rather believed that she offered herself to him to furthen her career and he rejected her. Tbh if Weinstein was capable to pick his victims wisely (not someone that would expose him easily) it may actually be what happened.
