its lazy and premature to discount genetics based on having npc family members. thats not how it works. Unless you have an identical twin you do not share all genetics with parents or siblings. Also there are genes that require a catalyst to activate, usually during development. Your preconceived notion that all shared experience would result in similar personality outcomes is based on identical genetics. Im sure many of us who identify as sentient, or aware, or able to overcome propaganda had a trigger before full maturity.
I myself was a libtard at 25, but that was due to having a simplistic grasp on geopolitics. Luckily i watched a documentary when i was 18 or so that gave me deep distrust for our government, and i carried that, and it overwrote anything to the contrary until i had a more complex worldview. My siblings, half being female never had a fucking chance, because women are by default not equipped to take such complex and abstract ideas to their logical conclusion when many are very uncomfortable and politically incorrect, their feelings will override any attempt.

TDLR its genetic, and early exposure to a trigger likely causes gene expression.
The key is young exposure to controversial thought, before decades of propaganda and preconceived notions become one's identity.
