I suppose its marginally better than the totally dehumanised 'thing with x reproductive/access/service providing points' like 'bleeders' and 'thing with uterus' (since the bloke informed us all that people meant specifically 'men', as if we didn't already know)
If we're using womxn (is a pronunciation guide being included in this?) to mean 'random group of mixed sex people who wish to be known by that term' then fine, so long as I can use 'woman' as 'biological female who wishes to be known by that term'.
