Aren't you forgetting all the intelligent Muslims, Jews, Hindus, Buddhist, Taoists, Sikhs, Shintoists and Wiccans etc?
Surely that means we must believe what they believe right?
I'm a smart person so believing in the celestial teapot I believe in isn't stupid apparently.
You see you can be smart. Exceptionally so and still do stupid things.
In a given moment in time every genius can appear stupid. Being smart doesn't mean you're smart about everything.
Many extremely intelligent people are dysfunctional in other aspects of their lives.
A common error with smart people is that because they are smarter about one two or ten things they can sometimes mistake their skill or intelligence to be universally applicable.
Worse than this, the many intelligent people that understand their own fallibility and folly then have less intelligent people mimic their choices in the assumption that if they are brilliant at X they surely make the right choices about Y.
How would anyone that relies on facts and research ever conclude a religion whose books are riddled with errors, it's stories ripe with illogical actions with depictions of petty vindictiveness born of small mindedness more akin to people that loved 2000 years ago would conceive than an almighty, infinitely wise god is truly beyond me.
It's quite amazing how so many poeple believe in easily refutable nonsense yet they are adamant their religion is the right one and when told of other religion they dismiss them as falsehoods and nonsense.
It's like watching children argue that their favourite superheroe would beat another.
It's all nonsense. Even if the smartest or dumbest persons in existence would be of religion X it would still be stupid.
Smart people do stupid things all the time. Think for yourself. Snake oil is easy to spot, I less you are 4 and it comes from your parent and some holy mumbo jumbo.
