I don’t think there is a born weak mind in that sense, it seems like an out or an excuse to me, we are all the same animal, and I don’t think will is purely innate or nature, all things are a combination of both with different ratios depending on the person.

I can for sure say my dad had a severe impact on me questioning things and doing my best to find objectivity before I form my opinion on things, which lead me to planting the seed of rebellion and defiance in myself. Be it religion, politics, philosophy, authority, or what have you, he never put his views into my head about it and encouraged me to examine things more deeply when I wasn’t. Indoctrination is a bitch, and he bent over backwards to make sure he was doing the opposite. A lot of personality is innate and unchangeable, but if you’re not fucked by that then ideology and opinions are malleable, it just depends on weather or not you’ve learned to be molded by others or yourself, and religious indoctrination from birth fucks up all of the gauges if there isn’t anything else to add influence, which I saw a lot as I also grew up around a very religious community that often shunned me for questioning, I was luckily taught self definition.
