So what/if/mammals cannot change sex

Irrelevant Comment: “Mammals cannot change their sex.”

Usage

the lone comment on an article about animals that naturally change sex, observing that none of them are mammals (presumably in support of the idea that Humans cannot change sex)

This point is typically raised in "gender critical" (GC) arguments against transgendrity. The sequence tends to go like this (TA = trans advocate):

• GC: Biological sex is immutable, so trans women are just men in dresses.
  • TA: But there are several species of animal which change their sex as part of their natural life-cycle.
    • GC: None of those are mammals. (Implied: humans are mammals, therefore this doesn't prove anything about humans, so humans still cannot change sex.

Analysis

Although most GC proponentsists will now skip directly to the hardened form ("humans cannot..."), effectively moving the goalposts, the claims that biological sex is immutable and that changing sex is unnatural will still sometimes be stated, in spite of being refuted by the existence of these animals. intellectual dishonesty
