Perhaps it is a truism that nothingness constitutes our anteriority. Yet the concept of nothingness inveigles into its structuration a tincture of romance. The need to trace abeginning, to locate a temporal point of reference is universal and perhaps without the need to go further back we would be subsumed under the very nothingness we seek to locate a fulcrum from. An all too human desire, with its attendant mythopoeia , confers an imprimatur of authentication of being but in the process crystallizes certain phenomena at the cost of negating others.
And it is this negation that becomes a valid mechanism for the homosexual phenomenon to asseverate its indubitable existence. Negation draws attention to its own negation and erasure. A dominant structure invalidates the threatening presence of things that are 'other' by 'othering them'. That which is disregarded and repressed as unworthy is a counterpoint to the indeterminate ontology of that which is there, masquerading as ubiquitous.
'Existence precedes essence' is an encapsulation of phenomena's intrinsically tenuous being. What comes to be is not necessarily what always was. Conversely what is seemingly invisible is there, only repressed in the unconscious as unprepossessing. What is being? one may ask and indeed the question poses more doubts than answers them. Can physical being constitute being? Or is the palimpsest of consciousness on which the paraphernalia of being is predicated is being. Are there two beings then, the bodily and the consciousness. The mind is seen by Locke as a blank slate. Yet the appurtenances of pre existent collective modes of being inform being. Are we then composed of a conglomeration of unlocatable ontology or what we mold ourselves into through reconfiguring all that constitutes us. Consciousness imbues being with meaning. Is consciousness then a precondition or is it a protracted acquisition. Modern scientists are in search of certain genetic combinations that would attest to the presence of propensities and proclivities that determine a homosexual being. As of now the edifice is highly precarious and shaky.
The more we eschew categorization the more palpable their ineluctability. Perhaps the homosexual being as it is or being for itself is a raison d etre, an incontrovertible affirmation. If our existence in our specific orientation is an unavoidable aspect of our being then homosexuality becomes a becoming that is both prefigurable and appropriable. The nature argument reduplicates the heterosexual presumption and as we have now, with post post modernism realized that the beginning of things is a chimera that recedes further and further the moment it is tentatively grasped. One is not arguing that one isn't born but becomes a homosexual. Born presupposes ontology, anteriority and all forms of polymorphous sexualities coexist. Can a homosexual orientation be based on being as birth itself. Genetics would putatively hypothesize thus but then becoming which involves amalgamation of disparate existential accoutrements as temporality progresses would undermine the 'i was born homosexual' paradigm. With the accumulation of consciousness knowledge is gathered. One is not arguing that one can't be born homosexual but merely saying that, given the unknowability of forms that would ratify this , it is perhaps better to look at things differently.
My tentative view, gleaned from queer theory and poststructuralism is that heterosexuality itself is not something one is born with. The physical being may be brought into being with an idea of an orientation but the associations that surround an orientation determine the dynamics. There is a vast pool of numerous concatenated orientations. Being there is, if one argues for temporal, physical being. Immutable being undermines essentialism. It doesn't matter if one born homosexual or becomes homosexual. One is what one has determined one's life to be. And as existence precedes essence it is perhaps sanguine to, in these times of constructs, value indivisible becoming as choice or as birthright to determine for an individual what he is.
