The root of antisemitism is serving humanity governing ancestors 24/7 with the idea genetic outcomes cannot be living eternally separated since conception of each next generation gap lived so far.
Every society in history practiced ignoring how genetic outcomes are never same details twice within results existed daily here.
Evolving is a series parallel situation for each genetic addition to the species. People honoring typecast social orders won't accept that outcome every day alive.
That is free will choices recorded in everyone's own ancestral lineage.
Doing the same social behavior for 350 generations within one species doesn't make that species exempt from the universal process of adapting to the moment here regardless formed by molecular content, social context, or ancestral lineages so far.
