There is no evidence that theism increases IQ or protects you from making a verbal fool of yourself. There are dumb theists just as their are dumb atheists. If my arguments in the OP are correct their may actually be relatively fewer low IQ atheists.
I agree that Richard Dawkins would likely disagree with some of the arguments made in this thread especially the ones regarding group selection for he is on record as opposing this idea. Other evolutionary biologists disagree with Dawkins on this issue.
https://en.wikipedia.org/wiki/Richard_DawkinsDawkins has consistently been sceptical about non-adaptive processes in evolution (such as spandrels, described by Gould and Lewontin)[37] and about selection at levels "above" that of the gene.[38] He is particularly sceptical about the practical possibility or importance of group selection as a basis for understanding altruism.[39]:169172 This behaviour appears at first to be an evolutionary paradox, since helping others costs precious resources and decreases one's own fitness. Previously, many had interpreted this as an aspect of group selection: individuals are doing what is best for the survival of the population or species as a whole....
Dawkins popularised these ideas in The Selfish Gene, and developed them in his own work.[42] Dawkins has also been strongly critical of the Gaia hypothesis of the independent scientist James Lovelock.[43][44][45] In June 2012 he was highly critical of fellow biologist E.O. Wilson's 2012 book The Social Conquest of Earth.[46]

Advocates for higher levels of selection (such as Richard Lewontin, David Sloan Wilson, and Elliott Sober) suggest that there are many phenomena (including altruism) that gene-based selection cannot satisfactorily explain. The philosopher Mary Midgley, with whom Dawkins clashed in print concerning The Selfish Gene,[52][53] has criticised gene selection, memetics, and sociobiology as being excessively reductionist;[54]
Edit: As an interesting aside from the wikipedia article it appears that Dawkins himself fulfills Charlton's triad.
Obviously high IQ (yep)
Socialism (self identified feminist and on record support of liberal democrats)
Atheism (self identified)
Low Fertility (only one child)
