No. In the case of the woman getting drunk, she's the one knowingly drinking. In the case of somebody slipping her a roofie, she has NOT knowingly and willingly consumed the drug. That is the crucial difference.
Women need to understand one simple thing: don't get drunk.
I'm tired of the feminist crowd, and their male enablers, absolving women of all responsibility for their actions.
Also, in the cases where women get drunk, have sex, and then have regrets, they generally were conscious of what they were doing. It's one thing to take advantage of a girl passed out in the hallway -- it's quite another thing to have a girl take the initiative to have sex, and then later claim rape when the guy doesn't call her.
The only person here absolving people is you.
