"The president of American Atheists, David Silverman, defines firebrand atheism as simply telling the truth about religion, with the emphasis on the telling. He says we should make clear that it’s religious beliefs we’re attacking, not the person. He says, “I’m not attacking humans; I’m attacking those humans’ silly beliefs.”The truth is not available to Silverman. He cannot prove the non-existence of a deity; he is not privy to that information or "truth". So he cannot be truthful by claiming to know the truth. This is a paradox, where the actual truth contradicts the claim of "truth".
Atheism is firmly based in this "truth" paradox; it always has been. It is a necessary condition for Atheism; one cannot be an Atheist without the de facto acceptance of this internal logical failure.
Atheists tend to revel in their "independence". The Atheist position of the gloriousness of being independent of external control is asserted by attempting to assert external control over others. And that is paradox #2.
A third paradox is the rigid belief in the superiority of themselves, since they have gotten their exclusive access to "truth" merely by rejecting outside authority. This allows them to swell with self-endowed elitism, even though true elites earn it, rather than self-administer the title. This, then, is a third paradox of Atheism.
While rejecting the hated "religiosity" of theists, these Atheists become rabidly evangelical in their attempts to convert the benighted small-minded into the religiously evangelical cult of rabid Atheism. Of course, this is internally contradictory, and is a fourth paradox of Atheism.
Most Atheists are known to nearly universally veer strongly politically Leftward. They are jealous of their own autonomy, and yet they endorse totalitarian processes which restrict the autonomy and thoughts of others. This obviously is another internal contradiction, a fifth paradox of Atheism.
Atheism also nearly universally hails itself as "rational, logical, and evidence-based". However, they are driven by paradox and are completely without out rational, logical or evidentiary proof of their own position, which is this: that there is no deity. That is a sixth paradox of Atheism. And because they have neither logic nor empirical evidence to support their truth claims, they do not engage in dialectic; they use rhetoric and all of the rhetorical devices which are outside the realm of logic and evidence. In rhetoric there are no fallacies; it is not logic based.
Atheists, and their organizations, claim Victimhood Class status for themselves: they claim they are oppressed by religion, especially in government. However, since Atheism has no principles attached to it, an Atheist government has no principles, certainly no moral principles, and thus cannot legitimately recognize any action as either moral or immoral, including the anti-intellectual claim of "oppression". So the Atheist claiming "oppression" in an appeal to an Atheist government cannot be "oppressed" according to that government. That is a seventh paradox of Atheism.
In the same vein, Atheists claim that religion is "evil". Yet Atheism has no common set of moral principles, and thus any concept of evil is merely non-existent at best and relative at worst. Thus the concept of evil is without objective meaning. So the Atheist claim of "evil" religion has no meaning under amoral Atheism. Here, then, is an eighth Atheist paradox.
Silverman is promoting "firebrand Atheism" which means screeching in high volume about God. But that's what Silverman hates: theists who screech in high volume about God. Yes, that is a ninth Atheist paradox.
Atheists claim that religion is the most dangerous belief. They ignore (no matter how often reminded) that the worst genocides and mass murders and tortures in history have been racked up by Atheists. And there is a tenth paradox.
Atheism is false, but it is aggressively pursuing the foisting of its logical fallacies onto everyone; Atheists consider the beliefs of everyone who is not them to be silly, held by silly, stupid people. This is the attitude of the Marxist New Man ideologies and the Nietzschean Uberman philosophy. It is classist, because they are the superior ones, in a higher class, by themselves, better than everyone who again is not them.
Viewed logically, without paradox or internal contradiction based in arrogance of presupposed intellectual/moral eliteness, it is quite clear that Atheism is the most dangerous ideology of all, if for no other reason than its irrationality, but also for its lack of moral grounding as the world has seen in Atheist nations ever since 1917. And denial of that objective fact involves still another internal contradiction.
