Every person has a worldview – principles, beliefs, and a school of thought by which one encounters and experiences the surrounding world and its events. Most of the time, at least in “Western” societies, this worldview is self-chosen.
A worldview forms and encompasses the process by which a person relates to general questions of life, such as – the world and its origin, what it means to be human, the method of human interrelationships, how humanity relates to the rest of nature, how humanity relates to the Divine (if the worldview allows for the Divine), and so forth. Even “unbelief” is itself a form of belief.
A worldview in a broad sense is religious, be it confessing the Divine or denying it; be it extremely organized or loosely structured. Religion in a general and modern sense is that which one takes as a guiding principle for life. Speaking in a mundane manner, it could be any belief system that provides a narrative for the inevitable questions of life that face almost every human person. In that broad sense, there are no nonreligious people because everyone has a belief system of some sort.
Inevitably tied up with belief systems are questions relating to humanity and human morals. A person will act, or at least strive to, in a manner that is consonant with his worldview.
In America (and the Western world at large) at this time there is a clash of worldviews, and this is at the root of the tension regarding human sexuality and its proper function.
Clearly, Christianity (when I use that word I mean traditional Christianity) has very clear teachings based on its worldview (ultimately, as I have argued elsewhere, based on Divine revelation) regarding the proper use of human sexuality.
On the other hand, Secularism has very clear teachings based on its worldview regarding the use of human sexuality.
Each view is based soundly on belief; a belief that is formed by a worldview.
Secularism claims to be neutral to “religion.” This claim is ultimately false and impossible because Secularism is itself a form of religion, that is it has its own narrative regarding the questions of life. As such it cannot be neutral, nor is it an unbiased mediator between other religions. Secularism itself carries with it a bias, as does any worldview. Secularism generally has a condescending disdain for other worldviews (religions) that profess Divinity and Divine revelation. The Secularist faith generally does not play well with competing faith narratives, a survey of the strong secularist states of the past Century reveals this. Generally, violent persecution or basic discrimination of other faiths, most of all those claiming Divine revelation, becomes standard practice.
Secularism generally professes an extreme humanism, that is everything is simply natural and there is no supra-natural. Even when a spirituality of sorts is embraced it is one focused on the human and its pleasures, desires, and satisfaction and not so much on the Divine. Most of the time, the Divine is there only to fulfill the wishes of the human. Thus it remains humanism.
The morality (using that word very loosely) of embracing and celebrating the LGBTQ movement and other sexual variations is directly grounded in the modern secular worldview. Moreover, it demands that all other worldviews accept its moral stance. The enforcing of June as LGBTQ pride month reflects this stance. Not very tolerant, by the way. Its message is that all other beliefs must submit to its belief system. Remember, morality and views on human sexuality and its use are products of a belief system.
Even when those professing to be Christians of some sort embrace and support the secularist view on human sexual activity, be it homosexuality or heterosexual promiscuity, they are willingly disregarding the traditional Christian view and embracing something foreign. The point being, an act of the will is involved. We, as persons, choose to believe certain narratives and disregard others. Is the Secular narrative truly more tolerant and loving? Will abiding by it truly allow everyone to coexist? Not really, it is simply a self-chosen belief system that a person embraces and it currently is demanding that dissenting views be rejected, silenced, and punished.
Ultimately, if humanity has no higher purpose and is simply in an ever general state of evolution then sexual evolution makes sense. But, if humanity is the unique creation of God, which has been created with great forethought and purpose, then proper sexuality is constrained by the standards of the Creator (which is the relation of one man and one woman in marriage). And God has made it abundantly clear in His revelation that sexual perversions, be they of the homosexual, heterosexual, transsexual, and whatever else, are destructive and wrong. I cannot celebrate the spiritual destruction of another person and I’m not very loving if I tell folks practicing such things that they will be just fine. In fact, I think, real love is to warn another person of forthcoming danger. We are warned as a race so that we might not destroy ourselves. As with any sin, God always invites humanity to repentance; that is a return to the life which He created for our race. Yet, we are always free to reject His invitation.
As marriage between one man and one woman is a fundamental doctrine for true Christianity, so acceptance and promotion of LGBTQ practice is a fundamental doctrine for Secularism.
Thus, the phenomenon of the LGBTQ movement is a religious one; it is based firmly on a very particular worldview. Thus far, I think we can expect more tolerance from the Inquisition than from it.
(Aside: the modern obsession with sexuality shows its paltry understanding of humanity. Sexuality is but a small aspect of human life, although one that according to Divine Revelation must be utilized properly, as with the many other aspects of human life. The LGBTQ belief reflects the fragmentation which the parent faith of Secularism inflicts.)
