It's common sense that if you don't want to be raped, you don't dress like a slut and put yourself around strange men. This would be equally true for rich white guys who want to travel through a bad part of town with a lot of money on them. Nature cares nothing for your "freedom." Put yourself in the path of a predator, behave like prey and you can expect depredation. That is pure causality.
A few weeks ago, the topic of the slut walk came up during lunch at my workplace. The other four people at the table, one guy and three gals, were in support of it. They mocked and ridiculed the cop who had told an audience to avoid rape by not dressing like sluts. I wasn't surprised.
It seems that common sense is not very common.
