You realise what you gave as an analogy is just another example of victim blaming, right? For rapes to stop, men need to stop raping. If a man rapes, he is to blame. Attempting to control women by telling them not to walk down alleys and then blaming rape on them if they don't listen to you is victim blaming.
Hello sociology feminist major. "Men need to stop raping"? That's not a prejudicial or offensive statement at all...
I would argue that those doing the raping aren't men, they're monsters. Women can just as easily be monsters; there have been many stories of women teachers having sexual relations with minors. Disgusting, right? Especially since they are in positions of power.
People need to be vigilant with how they conduct themselves in everyday life. So in the iCloud case, people, and especially celebrities, will have to be far more cautious with their password creations and account management styles. Should they have to be more careful? No, but they wouldn't be very wise then.
And going back to the other example from the poster you quoted: yes, absolutely, a lady should probably think twice about walking down the street of a bad area or neighborhood. While she absolutely has a right to walk down the street without being accosted, there are criminals and monsters out there and they don't care about anyone's rights...an unfortunate fact of life. We can all become victims just from minding our own business; this iCloud thing, again, is the perfect example of that.
Another example is if I drive an expensive car and park it in a shady area of town. I have a right not to have my property damaged or taken. Just because I have a right, however, doesn't make me invincible to the bad people out there.
The reality is we all (men, women, children, and celebrities alike) have the potential to be victims. So yes, there is a
small element of blame deserved if you've put yourself in a bad situation. Going through life saying "I'm empowered and you can't or shouldn't touch me" is just asking for trouble. The reality is we are all potential victims; if not victims of rape or crime, then victims of our privacy being invaded by hackers or the government. Unfortunately, it seems like witnessing such terrible things is the only way to learn how to be more vigilant. Awful, I know.
Now that there are victims in this iCloud scandal, it's up to the rest of society to find and punish these monsters.
