The original meme is about women feeling they are less threatened by a bear than a strange man, the bear might leave them alone or not be aggressive where a man would be more likely to. That men can be a threat in different ways.
Separately men very often discuss what animals they could beat in a fight. This results in a misunderstanding/disconnect between “who would you feel less threatened by” and “who would win in a fight”, which I agree is not what the original meme of women “choosing the bear” is about, but it is a very similar dynamic that results in men explaining that you won’t win a fight against a bear. Which, again, is not the point of the original meme indicating a feeling that a bear might be less likely to harm or threaten you, which is why it results in people talking past each other. (Kind of like right now…)
