Even if 99% of men were not abusers, the 1% that are also tend to hide their malice and pretend to be decent until alone and the woman is vulnerable. So as women interact with hundreds or thousands of men over their lifetimes they will come across these abusers or know someone who was abused and that the system blames victims and the fear is not just about percentage chance of a horrible outcome, but that society continues the abuse.

A bear is a known factor, dangerous but never in a deceptive way and society doesn't tend to blame victims of animal attacks.

Also the percentage of abusers is way higher than 1%. Everyone knows multiple rape and abuse victims, but few people know someone who was mauled by a bear. That is the context for this question.
