I think this is a core issue in this thread. Terms like 'brainwashing' suggest that those who still hold on to religion are somehow kept 'superstitious' by others or by how they were raised. At least in the society I live in, many leave church when they are adults even if they were raised being baptized and confirmed, whereas others choose to stay a member of their church. Even if one is raised religiously it doesn't mean one can't put everything into question when growing up, make up one's own mind, and it doesn't necessarily lead to quitting church.
