Let’s take a look at the logic underlying such claims.
Either a person has heard the posits of a creating deity, or he has not.
If not, then he is ignorant.
If so, then he knows the posits.
If a person knows the posits about a creating deity, then either he accepts them or rejects them or cannot decide.
If he cannot decide, he is an agnostic, not an Atheist, yet he either has reasons and reasoning, or he does not.
If he rejects them (Atheist), either he has reasons or reasoning, or he does not.
If he does not have reasons or reasoning, then he is not rational in his rejection.
If he does have reasons or reasoning, then either the reasons are comprised of disciplined logic and/or material evidence, or not.
If not, he is not rational.
If he has rejected the posits using disciplined logic and/or material evidence, then he can present that to support his rejection, or not.
If not, he is intellectually dishonest, and doesn’t want his disciplined logic and/or material evidence examined, analyzed and refuted.
If he doesn’t want his disciplined logic and/or material evidence examined, analyzed and refuted, then he is either an intellectual coward, or he knows that the logic and material evidence are false (intellectual fraud). Both of these eventualities indicate emotional disturbance in that individual.
Since Atheists do not ever present either logic or evidence which prove categorically and incorrigibly that the posits of a creating deity are immutably false, then it is proper to assume that either they do not actually have either logic or evidence to support their rejection (This is supported by the Atheist belief in “Hitchens’ Razor”), or they are intellectually dishonest. Or in this case, both.
If they claim mere “disbelief” without any responsibility to support their position with logic or evidence, Then it is proper to assume that either they are intellectually dishonest in their claim, or they have no reason or reasoning in their disbelief. Both of these are intellectually empty positions. Both of these are universal amongst modern Atheists.
Here is a simple form of a posit of a creating deity:
Either the universe always existed, or it came into being.
If it is thought to have always existed, then a) it is an infinite regression (fallacy); b) the Big Bang and Expansionary Theory is a false theory (anti-science).
If the universe is an infinite regression, then empirical evidence is needed; there is none.
If the universe came into being at the Big Bang, then empirical evidence is needed; that evidence exists.
If the universe came into being, it violates the null hypothesis that “nothing” is more parsimonious than is “something”.
If the new existence of a universe is less parsimonious than its prior non-existence, it is proper to assume that there is a reason that the universe came into existence, overcoming the null hypothesis. That reason correlates with a cause, pre-existing the material universe, with the power and causal ability to create the universe, and is therefore greater than the universe.
Further, that causal power had a reason to create the universe, and therefore was an agent.
Further, the creating agent created the rational laws for ordered material existence which were installed, rather than mere chaos, when chaos (non-ordered) would be the null hypothesis. Given the existence of rational laws for ordered existence, then the creating agent is rational.
Therefore, it is more rational to conclude that the universe came into being in opposition to the null state of non-existence, and it did so due a creating agent which is sufficiently powerful, purposeful, and rational.
Now, this argument can be rejected by Atheists who are not ignorant of it, for two possible reasons: 1) rational objections using disciplined logic and/or material evidence, OR 2) emotional reasons. But the Atheist cannot claim to have NO reasons or reasoning, to have mere disbelief without cause for disbelief, without also being obviously intellectually dishonest and emotionally based, and completely without any intellectual content in his position.
Atheism reduces and resolves to blind belief that there is no creating deity, and does so in the complete absence of disciplined logic and/or material evidence; in fact it must deny disciplined logic and existing material evidence, in order to maintain the blind belief.
