I believe (albeit cannot prove it) that cognitive predispositions are the hardware rather then software - i.e. are predetermined by the chemical and neurological setup of a person's brain, rather than learned. That does not mean they are necessarily genetic - perhaps pre-natal and early childhood environment has something to do with it. Mind that cognitive predisposition affects not just the choice of political ideology (a relative minor affair but how we organize our perceptions in general.
BTW, this view is not functionalism of any sort but "innatism", close inter alia to Noam Chomsky's linguistic theories, which rebuked functionalism and behaviorism. In short, the behaviorist/functionalist view is that human being is a tabula rasa at birth and all his/her knowledge is acquired through experience or derived from via repetition, reinforcement, abstraction, generalization, recollection etc. Chomsky believed that this was a bunch of crap that does not hold water and proposed a view that people are born with innate cognitive dispositions which are then activated and shaped by experiences. I am with Chomsky on that. I hope that neurological science will vindicate us one day.
As to calling cops on abusive husbands, a friend of mine who lives in NJ had once a visitor from Poland - a brother in law, to be exact. The guy tried to talk her hubby into some sort of shadowy deal in which the hubby would provide capital and the brother in law - brain power. The hubby was a nice a guy but a doormat, and he was ready to cough up a few grand, but my friend intervened saying that this was also her money. To which the brother in law replied "Shut up, woman, my brother and are doing business." My friend asked him to leave, but he laughed saying that this was "his brother's house." My friend told him that if he did not leave immediately, she would call the cops, to which the brother in law replied that they would not bother with "domestic affairs." My friend called 911 and a few moments later two cops appeared, handcuffed the guy and asked my friend if she wanted to file criminal charges. She did not, just wanted him out of her house. The cops told the brother in law that he was free to walk but if he showed up in that house again he would be immediately arrested and deported (he was on a tourist visa.). The brother in law was in absolute shock and was not seen in my friend's house again.
