I don't think most people literally believe every man is stronger than every woman.
I think it's much more common that someone will say "of course there are some women who are stronger than most men" then go back to tending to, for example, hire men over women for a job requiring the ability to lift 60 lbs, without bothering to strength-test female applicants.
