Quoting Langcleg from that thread who sums this issue up and illustrates the poverty of the circular definition such as favoured by the likes of RatRolyPoly and their fans:
I identify as a schnargle. What is a schnargle? Anyone who identifies as schnarge.
Are you any the wiser as to the nature of schnargle? No, you are not.
If you can't define your terms; you can't demand legislation and social policy because they will be unworkable and default to extant power structures - in this case, the patriarchal power structures which benefit males. This is why extremist transactivism is a male supremacist political movement.
