The fact the you just blamed the victim by saying it's their fault shows that it is common in the States. Most rapes are about control, so the messed up people who are rapists think that have to put women (and men) in their place. It's not the victim's actions but how people react to them that is the problem-worldwide.
No, he didn't "blame the victim by saying it's their fault", and the fact you claimed he did means you are part of the problem. Look at it this way: if I drive a Porsche into a bad neighborhood, leave it unlocked with the keys inside, and it gets stolen, are you going to say I didn't mess up? No, of course I messed up, because failing to lock the doors on your car is stupid. That doesn't mean I'd bear the responsibility for the car being stolen, but it does mean what I did was stupid, and I would partially bear responsibility for a chain of action that lead to the car being stolen, and I could maybe have prevented the car being stolen. Since I cannot control the actions of other people, only my own, what I can do to prevent my car from being stolen is to take the proper precautions: lock the doors, don't park in bad neighborhoods, install a tracking system, etc.
For women (or men: rape works in both directions, though it's generally a vastly worse problem for women, especially attractive ones), that means not wearing revealing clothing while drunk at 3AM in a bad alley, watching their drinks closely, only hanging out with groups of people they trust and know well, etc. None of that means they're the ones responsible for the rape if they do get raped: but it does mean they can lower the probability of rape happening by being smart, and since the goal is to stop rapes from happening, we should encourage them to be smart, and discourage them from being stupid.
In other words: we can't blame the women for being raped, but we certainly can blame them for being stupid. Yes, everyone should be able to be as stupid as they want with no fear of other people doing bad things to them, but so long as we live in the real world, that will never happen (though we can still strive towards it, of course), so we should tell people to stop being stupid, because that means bad things are less likely to happen to them.
