Looking at it now, it seems he WAS actually arguing FOR censoring stories of the bad behavior of the gods AND FOR censoring Homer's Odyssey.
Sigh.
Our state is built on the narratives of democracy and equality thus while those factors have ability to undermine the narrative (as we've seen in not so distant history) we have to censor them and do the research behind closed doors, otherwise we risk more damage than any possible benefit.
Pretty verboten topic though and kind of unpalatable to think about, even if you don't particularly care about these sorts of demographic shifts.
Personally I like that the whole idea of "race" might become increasingly indeterminate and vague in liberal societies.
The phenomenon is real but for fully understandable reasons not much is published about it.
mRNA can change gene expression locally for limited time, enough to train your immune sysem but not for permanent changes. CRISPR can make permanent changes but but for now only to few cells in vitro, not to whole organism. Even the Chineese CRISPR modified twins are mosaics of modified and unmodofied.
Also even if a study found parameters like that, it would never be published as the scientists career would absolutely be ruined.
