The problem with the "victim blaming" concept is that it prevents us from giving good advice about how to avoid being a victim. It's clear that women shouldn't stay with male strangers. Men should think carefully about it too.
It's not about blame. If someone drugs and/or rapes someone else, that person is to blame. But it is possible to avoid situations where you're vulnerable.
