Clearly, the whole isue of gender identity and ideology is a major cultural and social topic at present, and from that there arises conflicts and disputes over the nature of reality, biology, the facts of the sexed body; and how all of that impacts upon the rights and protections afforded to women and girls, particularly.
That Sam Brinton uses the term 'non binary' to indicate a very specific kind of identity - and in such a very prominent and public facing role - obviously highlights all of the above in the public mind.
It is clear that this person is not only confused but also struggles with disordered thinking/ a fetish, that leads him to steal women's suitcases and and then appropriate their clothing for his own needs and desires. He also does this in a very public way. He is not stealing women's underwear from the washing line and using the items in private; he is targeting specific women at airports and then wearing their clothes in a very ostentatious and one might say exhbitionist way. He is flaunting his fetish to the public.
I read that he claimed he was disowned by his parents for being bisexual ( I suggest he is simply gay - but saying bisexual affords some measure of validation for 'cis heteronormativity') and subjected to conversion therapy, though some of his claims have been disputed. He is clearly struggling with intense internal contradictions of the sort that lead him not only to criminality, but also to highlight the deep confusion that now permeates American society, when it comes to matters of sex, 'gender identity' and sexual orientation.
This 'queering' of society has some deep and dark down-sides.
