I'm interpreting them as conduct being actions, and orientation being desires.
Sex isn't a powerful force for some, but I bet that many who were told "you can't have sex for your whole life except with those you don't find any attraction to" would find it very difficult to follow. And that's what's being told to homosexuals who might be that way from birth.
Does that mean that they have no control over what they do? No...but if a person's underlying sexual desires are suppressed, I'm sure there are some effects to be addressed in counseling. For a counselor not to have exposure to that is to mean she has an incomplete understanding of those who might seek her professional services.
The best answer for a counselor to give such a client (whose sexual desires are being repressed—oh such a tough situation in today’s world when according to TV a human is supposed to be akin to a guppy) is this: “God knows your struggle and your pain. It is best to remain single and devote yourself to God’s work, but if you are worried about committing sexual sin, pray and God will find you a wife (or husband as the case may be) but you will have trouble in that relationship.” All Biblical.
Watch the You Tubes of Bishop Sheen. At the end of each of our lives either Satan will be there to claim you or Jesus will be there to you; “Mine.” It is very riveting.
So basically, there is no secular.
If you read through or listen to the New Testament, time and time again, the prohibition of sexual sin is repeated. It is not enough to be kind and generous and continue to sin sexually. A person must do it all.
So Gondring, I do not know what your deal is, only that your ideas are very fluid, shall I say. Further study is what I recommend.
I would say that most homosexuals are made that way after birth, perhaps through some trauma (molestation). In these cases, counseling is certainly indicated. Many cases involving cured homosexuals are known.
However, there may be some cases of people being born homosexual, perhaps through the effects of hormones in the womb. Perhaps counseling cannot help these people to change. Nevertheless, I would expect them to control their behavior. I do believe that humans have free will and that those who engage in improper behavior (and we all do) need to recognize that "My behavior was wrong".
It is my belief that our society discourages the idea that homosexuality is wrong and that, today, most homosexuals simply do not recognize that they ought to try to not live that lifestyle. This goes for those who are "born that way" or those who were not. Acting upon the desires is always a choice, and if society doesn't tell then it is a bad choice, then society is not helping them.
