I so agree with many points in this thread particulary the degree of social control Jehovahs witnessess exercise. Can social control and culture be seen as the same thing?
If so then perhaps Nietzsche can aid us to contextualize our situation. He said that culture has a training effect and this effect is important for development. But the person responding to cultural training also needs to be able to step back from it and say yes to any paths that he/she himself/herself wishes to explore. Stepping back and cultivating the ability to agree and disagree is very important but this is not allowed by Jehovahs witnessess. So I would say that we did not fully choose to follow their crap advice as Jehovahs witnesses do not allow members to consider other options. Everything other than Jehovahs witnesses is presented in a negative light and one is expected to live life in this negative negating way. I guess this aspect could be seen as mind control and social control.
On the other hand by becoming a witness and remaining a witness we are exercising choice to some extent in that we are saying no to the culture around us and yes to JW culture. Or perhaps the reason we became witnesses is that we were aware of a lack of a strong sense of culture outside of witnessess. This is something to think about as many (non JW) people object to the path modernity has taken. Were we objecting to something like modernity when we became Jehovahs witnesses?
