It's far worse than the article indicates. Secular humanism is only a tactic, not the goal. The progressive left is the world's biggest Gnostic cult. Scientism is their philosopher's stone; the "Lost Word" seeking to transform lead into gold, a metaphor of turning humanity into gods (or Transhumans) and immanentizing the Eschaton (we are the ones we've been waiting for..."fundamental transformation"). Science is magic and miracle in this system. Witness the "transhumanists" and the quest for immortality. The calls for a "scientific dictatorship" from HG Wells to Richard Dawkins.
When "citizen of the world" Barack Obama told an eager Berlin audience that he saluted the "divine spark within us all" he was simply reiterating the Gnostic cosmogony spoken against by St. Paul and St. John in the New Testament.
In this worldview, it is compassionate to abort babies, since material existence is the true evil and who would wish to punish women with babies, or punish babies with existence. Pessimism is the surest sign of Gnosticism. This world is not a good world corrupted in the fall of man, you see. This world is evil because it's materiality is itself "separation from the Divine Spirit". Material wealth is the sign of a necessary evil (necessary for the Gnostic gospel to proceed in all realms of influence); that, unless used to spread the ancient anti-philosophy of the Luciferians, must be countered, confiscated and defeated.
The family, faithful Churches, true philosophy and patriotism are all impediments and delusions in this system: delusions that keep the ignorant (non-Gnostics) from embracing their truest selves, which is as an emanation of the "collective soul". Individualism is evil because it hides the "true nature of reality" (we are One) in selfishness. Therefore, individual salvation does not and can not exist. Recall Mr. Obama's assertion that his individual salvation was dependent not upon himself or his "god" but upon collective salvation. This is the root of the progressive faith that government must solve all problems...the "collective will" must solve all problems.
The secularist pose is just that, a pose. The goal is Luciferianism, complete with rituals, sacrifices and a new age (ancient) hodgepodge of mythos that all, metaphorically and symbolically, tell the same fundamental story: "ye shall be as gods."
Witness the ease with which the left literally idolizes their leaders, from the cult of Rousseau, Napolean; Lenin; Stalin; Mussolini; Hitler; through the "self-actualization" cults of Astarte in the 20's to Guyana, the Family, the Process Church, the Manson cult and Heaven's Gate; to the faux-Greek "Throne of Pergamum" complete with rays-of-the-sun emanation/iconography for the One, Barack Obama. Even the pop versions today and their admiring press calls them "rock gods" and "Divas."
We're in big, big trouble folks. This isn't secularism.
