It can be inferred that you meant it to apply to a larger population because you mentioned it in reference to Nick's sister. So unless Nick's family are people you grew up with, you are implying your experiences hold true for most people.
I mean, I get that that's not your main point. But I think people are reacting to it strongly because you seem to be saying not, "Most victims don't go to the police," but rather "Most victims don't go to the police because it basically happens to everyone and is something you just deal with." Idk if that's what you meant to say, but that's how it reads to me at least.
