My advice is to never use the God argument
Except the point was never to explain why I believe abortion to be wrong, but whether beliefs of this kind can be held to be absolute. There's no point for me to be explicit about my beliefs if i cannot get you to accept the very premise upon which those beliefs are predicated upon. Of course, it bears repeating that the main issue in those polemics is not abortion as such, but the relativism pushed by the pro-abortion camp, against which religious fideism, which is lacking of a fundamental metaphysical underpinning, can only partially refute.
It is the same deal with the issue of homosexuality. What troubles the religious person is not homosexuality as such, but this idea that there's nothing inherently "wrong" about the homosexual act in principle as in fact. Since the religious exoterist only has faith and dogma to rely upon, any attempt to defend an idea which he can only perceive instinctively without any true conscious participation will automatically degenerate into an "hardened" absolutism which is lacking in nuisance and can even degenerate into a crass literalism and a petrified and suffocating fundamentalism which often ends up vandalizing the good it seeks to protect by perpetrating a greater evil (such as in the persecution of homosexuals). Basically, in order to defend himself from the relativist error the religious fideist errs in the opposite direction. In a sense, I even agree with many of criticisms regarding the inconsistencies and hypocrisies of the religious right. But then, if both sides of the argument are inherently full of sh*it, how do we determine what is true, and what is false? From a metaphysical point of view, the error of homosexuality can be explained thus:
sacredweb.com/online_articles/sw12_editorial.html
"The homosexual error is, among other things, that of isolating one pole of a binary cognate and treating it as an absolute, which does violence to the imperatives of the cosmic order"Anyone who understands the metaphysical underpinning of this argument will not seek to extirpate homosexuality in fact, particularly considering such a thing is basically impossible, but will attempt, as best as can be hoped for in this world of corruption, to uphold the norm and respect the natural equilibrium of the cosmos, the specific object of tradition being that of recreating this equilibrium in our earthly existence as well. This is what makes marriage a sacred rite, this institution being merely an attempt to recreated on earth what exists eternally at a divine level. Hence, why the "normalization" of homosexuality (and not homosexuality as such) is seen as a threat, since it seeks to subvert the norm directly while rendering the entire concept of marriage redundant in the process. I don't need to point out that the the same argument can be applied to the issue of abortion as well.
