Unlikely, considering TMP was made in 1978.The whole idea of Ilia with her pheromones and her ability to ensnare men with her sexuality in a teenage boy's dream. You can't probably get more sexist than this particular fantasy of GR's.
IMO its only Kambatta's sweet-portrayal of llia that counteracts Ilia's sex goddess role.
IMHO, Deltans represent the swinging 60s free-love mindset.
There are still some leftover hippies even to this day who never changed, you know? People's attitudes don't necessarily change just because the decades flip over. And certainly there is some residual hippie attitude even in TNG, as it morphed into political-correctness.
