Undoubtedly, this will prove upsetting to those who resort to challenging taunts of "give me proof", but who, in their eternal love affair with argumentum ad ignorantiam, deny all evidence presented.
Having thus exhibited their profound self-obsessed bias toward obdurate ignorance, creationists will almost certainly proceed on to whining that we atheists are "mean" to them for noting that they are more often less "bright" than atheists.
Why are they?
We are almost all raised within one religious tradition or another. Those who think rationally about the utter lack of evidence are more likely to deconvert than are those who do not think critically.
The IQ discrepancy would be even greater were it not for the fact that some individuals adopt atheistic attitudes for purely emotional reasons.
Since creationists repeatedly, publically demonstrate their poverty of logic, lack of education, or blatant intellectual dishonesty, they have no reasonable grounds for accusations of unfair labelling as being less intellectual than most atheists. End of story.
I make no apologies for the fact that I do not respect ill-founded, prejudiced, opinions that reflect an obsession with personal salvation, but which are typically accompanied by hypocritically anti-social attitudes.
People are entitled to their own opinions only in so far as it is impossible to alter the opinions of a person who is immune to evidence and logic. That is, the reality is that we are stuck with religiously-motivated ignorance. This does not mean that we must afford unwarranted respect to stubborn manifestations of a cognitive disorder. In fact, I think that we should not even feign respect for ignorant, biased opinions. Society can no longer afford to mollycoddle stupid ideas.
This is not to say that believers should be personally disrespected. It is to say that their uninformed notions should be refuted. Even though creationists almost never admit, let alone see, that they have been refuted, bystanders might benefit from having light shone on someone else's cognitive errors.
