Have you ever been punched by a man, Catherina? (I sincerely hope not.)
It's quite stunning, often literally. The strength of a male, past puberty, is phenomenal. Even small, weedy men.
I am staggered that anyone thinks that 'men are stronger' is a problematic statement, anymore than 'men are larger' is problematic. Simple statement of fact.
Given the facts, it seems dangerous to me to teach or suggest that there is no difference in the strength of males relative to females. This could easily lead to situations where females are put at risk of serious injury.
