The reason people sometimes tend to say the victim is blamed is because they say one of these things:

1. Well, she shouldn't have been wearing that provocative outfit, so she asked for it.

2. She shouldn't have been walking at night (to any destination, even if it's her car in a parking lot, etc.)

3. She's sexually active so of course she wanted it.

4. She shouldn't have been at (fill-in-the-blank).

That's why people say the victim tends to be blamed for the rape.
