No. Defending homosexuality is a rationalization process by which people attempt to normalize deviant choices that cannot be justified through any psychological exercise.
Homosexuality, though I disagree that it even requires justification, can be justificed biologically and psychologically through numerous studies, observations and experiments. What you really mean to say is that it cannot be justified through any psychological exercise strictly carried out within a Christian paradigm of thought.
As for the assertion that an attempt to normalize deviant behaviours implies the blanket immorality of abnormal behaviour, normality itself is simply an accepted consensus on what is considered typical behaviour, and it has no bearing on a thing's instrinsic moral value unless related to the various circumstances surrounding it. Deviation from normality is not evidence of immorality.
This is simply an attempt to placate a conscience that cannot harmonize the thing one desires and the moral limitations that prohibit the behavior.
There's no cognitive dissonance between my conscience and my opinions on homosexuality. I don't need to placate my conscience on the issue. The only reason a person might suffer cognitive dissonance regarding the issue is if the conscience is conditioned by accepted religious ideals.
Homosexuality is not a biological issue, it is a sin issue.
There certainly are biologial factors. I don't think the biology of homosexulity has to be mutually exclusive against any religious individual's acceptance of the bibilical sinfulness of the behaviour.
It is not socially acceptable behavior, it is a social and moral disgrace.
To you, perhaps. This is again, though an argument from popular opinion, and I can use exactly the same argument in support of homosexuality.
Homosexuality is not an illness nor is it some type of genetic abnormality.
Which scientific research paper did you read that in?
It is certainly not engineered biologically at birth. Homosexuals are NOT born gay.
Geneticists would disagree with you.
This is nothing more than an attempt to appeal to the scientific community and call them as a witness against the defense of scripture to defend this perverted behavior.
Reputable scientists don't attempt such petty and futile endeavours as setting out to attack or disprove the metaphysical by study of the physical world. You might also recognize reputable scientists study these things to find out information about the human body which offers explanations as to the biological reasons for certain hormonal or genetic occurences, not to presuppose conclusions. Facts gleaned from physical experimentation and observation under the scientific method shouldn't make conclusions about metaphysical premises, nor do they in scientific journals. Contrary to your belief, the entire scientific community doesn't revolve around you and your metaphysical beliefs.
Homosexuality is a learned behavior and a matter of choice, not a predilection.
Is heterosexuality?
There is no "pride" in it, nor should it be afforded any measure of dignity.
If you don't afford dignity to others, you don't deserve it afforded to you, but thankfully we live in a society populated by people far more forgiving than that. I have no desire to take away your dignity, even if you are quick to take away someone else's.
Homosexuality is SIN and in the end it will destroy all who engage in it or stand in its defense.
And by that logic your sins (of which we all have many) will destroy you just the same.
Attempting to explain it away scientifically is simply an attempt to excuse the behavior and marginalize it's shame.
''Marginalize its shame''?
Positiing scientific explanations is to posit a scientific explanation. It is an attempt at positing a scientific explanation. Contrary to your opinion, a geneticist doesn't write a paper on the polymorphism evident in the genetic markers of the x-chromosome in gay males to discredit religion, but to relay their scientific discovery. Make of it what you will.
