What is your point about not knowing about other faiths that cripples these people? How are they more mentally stunted they yourself? You dont even have a faith, so who are you to preach?
And there it is. Why shop? Because then all you're doing is picking up a habit from someone else. No different than a family recipe or some other tradition. You do it because it's what you know and it's what you're comfortable with. By and large, religion-wise, people are whatever they're introduced to. There's no independent thought. If you're born into a Catholic family, you're Catholic. If you're born into a Jewish family, you're Jewish. If you're born in India, there's an 80% chance you're Hindu. If you're born in Ireland, there's an 87% chance you're Roman Catholic. If you're born in China, there's a 78% chance you're Buddhist. If you're born in the US, there's an 86% cance you're Christian. These religions all have meaningful differences, yet, people by and large just end up following the predominant religion of their community. If there was any real measure of independent thought and analysis, you wouldn't have country after country, region after region with 80% of its population subscribing to the same religion.
