This whole scenario makes total sense to me. Try to put yourself in the role of the woman:
Man vs bear, random encounter alone in the woods. Both can easily overpower and harm you.
With the bear, you know it's one or the other, it either is going to be scared off by you yelling at it, or it's not and it will very quickly kill you.
The man, if he intends no harm, cool. But if he does intend harm, it can be impossible to tell. He can lie to you, appear friendly and helpful, all the while plotting to harm you horrifically. The bear can have no such malice.
The bear will not target you because of your race, sex, political views, gender identity, sexuality, or nationality.
The bear won't pretend to be your friend to lure you into a sense of false security. The bear won't become enraged at something you say and all of a sudden turn on you.
The bear has no fragile sense of ego that it will attempt to assert if it feels you "wounded" it in some trivial way.
A bear cannot be brainwashed by toxic propaganda or cultural norms about gender roles. A bear will never have any sense of sexual entitlement.
A bear won't drug you and assault you, a bear won't call its friends to join in when you are vulnerable. A bear won't hold blackmail against you after getting you drunk and manipulating you.
If all women had to do 99.99% of the time to scare away dangerous men was stand up tall, puff our their chests, and yell loudly, I doubt we would be having this conversation.
