Nothing you said refutes the fact that biological sex classification is 1) useful 2) has and continues to use the terms “male” and “female” for all species 3) such classification are scientific descriptions, not social constructs at all.

Reproduction is quite well documented and known, it isn’t some abstract thing that society made up.
