There are some very intelligent folks in organized religion, just watch the telly....how many money grubbing evangelists there are on the set.
But as for intelligence level versus participation in an organized religion, well, we could be arguing this for another 1000 years.
Personally I am not gonna say that only a retard would go to church.
On the other hand, I also would not say that someone who can see over the bullshit will or will not go to church either.
Faith is individual - regardless of intelligence or any other statistical analysis. And as such cannot be considered in any form a constant - which negates the entire argument.
I will say though, I personally have no faith in organized religion - PERIOD
Why not have faith in General Motors or General Dynamics - there is no difference.
And believe me, there are people who have undying faith in those organizations as well.
Did that answer the question or did it add to the confusion? LOL
