You can choose your ideology, but there is an obvious influence of societal defaults.
If you are born in Mecca, you are very likely to become and stay Muslim. If you are born in coastal California, you are very likely to become a Democrat of leftist bend. If you are born in a small town in the English Home Counties, you are likely to become a Tory. If you are born in a Catholic part of Northern Ireland, you are likely to become a Sinn Fein voter etc.
Obviously this isn't anywhere near as sticky as your skin color or even your primary language of communication, but the defaults are still rather strong.
