    WTF you really won’t go as far as non-separated at birth twin studies, will you.

    There is 100% confounding between nature and nurture when people grow up in the exact same niche with their siblings and parents. It is also notoriously difficult to separate the effects, even the so-called heritability index is probably statistical hokum. Twins separated at birth are your best go to separate the effects, and it is subject to criticism as well for confounding effects. Yet you go out in complete confidence and state that parent politics are hereditary. Ridiculous.
