Man vs bear isn't sexist. At it's core, it's a recognition that for human women, our biggest threat and predators in life are human males.
It's not sexist because plenty of men choose the bear for the same reason, either for themselves or for their children.
If men are choosing the bear as well.....it's not sexist.
It's not an unfair mischaracterization. It's a tecogbition of a universal truth. It's a highlight of a very real oroblem that has been ignored and swept under the rug for far too long.
