You actually think homosexuality is defendable.<quoted text>
... Do have a good day.
It is one of the few behaviors that violates BOTH mainstream religion and nature's function of our genitals for the purpose of human reproduction.
Homosexuality IS found in nature. But this doesn't challenge the behavior as justifiable as animals have been found to do many abnormal & destructive behaviors. Just as many animals have inherited genetic defects, so too has the reflex of these defects been observable within their behaviors. Homosexuality is certainly one such behavior.
From an evolutionary perspective, as Richard Dawkins puts it, genes are 'selfish'. Genes in a sense are desperate to survive, and so healthy animal psychology will be permeated with thoughts of heterosexuality in order to promote continuance of the species.
In fact, males and females have inherited (in general) antipodal characteristics to MINIMIZE homosexual attraction. In addition to enhancing the proverbial hunting and gathering, everything from the added bass in male voice, masculine body chemistry producing male scents, larger more powerful body, to substantially thicker body and facial hair, all serve as 'ornamentation' to create gender differentiation and consequentially it's reciprocal attractions.
Thus in example, many women will be irrationally turned on by facial hair on a guy, but men will generally be disgusted by facial hair on a woman.
Homosexuality is a disgrace to the will of natural selection. It's a 'bottle cap' preventing otherwise potentially intelligent productive people from passing the legacy of their genes to the next generation.
