The nail polish gives a warning to women who are given the drug, so that they can easily call out for help. No one who supporting it is saying it is 100% women's responsibility to stop rape. This nail polish is probably similar to a burglar alarm. Not your fault, but it gives a signal so one can get help and prevent the bugler from stealing your bloody dignity.

Why the hell are they complaining? I mean, you don't leave your door open and complain when you get robbed because the robber should be the one knowing he isn't supposed to do that. They need to do their part to avoid it as well.
