To be honest, I was thinking about the man who was trying to show me his penis when I was hiking in the woods a couple of weeks ago, when I heard this question. He was white. Actually all men that harassed me were white, thinking about it now.

Racist stereotypes are a real issue and I am not trying to deny that. And if women needed to imagine some hypothetical situation when thinking about dangerous men, you might be right. However, I think you might be underestimating the number of women who have been harassed, or worse. Most women do not need to imagine, they can just remember.
