Strange, the most celebrated people ever to live in the world have often been theists. Ardent theists, too, some of them.
Do you think Copernicus was intellectually stunted? Göedel? Do you think Mr. Rogers was emotionally stunted? Do sweeping generalizations usually make for nuanced views?
Please don't denigrate the attributes of people whose commonly held beliefs are unrelated to those attributes. Theists may be wrong but they not are inherently vacuous, malicious, or otherwise mentally deformed.
And a lot of people have religious reasons for not eating meat.
