I think you are asking the wrong question based on a faulty assumption. This whole business of "the dimension of spirit" is entirely subjective and therefore not the appropriate basis for determining if something is "moral" or not.A moral act, therefore, is not an act in which some divine or human law is obeyed but an act in which life intergrates itself in the dimension of spirit, and this means as personality within a community.
With this quote, I raise the question, "Is one's sexuality, in its self, a moral issue? And if so, how does one's sexuality become immoral?"
The word "moral" is defined in many ways and all of them are based on the idea of right and wrong behavior. Is it moral to kill? Depends. If you are defending someone who is under attack and kill the attacker thus protecting the innocent then the action is moral. If you randomly shoot at children on a playground, it is not.
Why? Because the ultimate purpose of morality is to maintain the greater good of humanity at large. This is why slavery is immoral but employing people at the lowest wage that they will accept is not.
With regards to homosexuality - if the human population was a meager 1,000 people then homosexuality would be a really big deal simply because as a species we want to survive and grow. With 6 billion people on the planet, that's another story.
It is similar to biology. A certain percent of the population will have biological anomalies that make them weaker than other people or stronger than other people. In a low-population society, this plays out by the strong surviving and the weak not. In a large population society, the importance of being the strongest becomes less of an issue. There are enough of us who are of average strength who will care for the weak.
So, the answer to your question is that there is nothing about the current population or society in general that can be harmed by homosexuality provided that relationships are monogamous. The real danger is in polygamous relationships that result in the spread of diseases such as HIV. This happens in both homosexual and heterosexual relationships but far more often in the former. If there was a cure for these std's, there would be absolutely no basis for a moral pronouncement against homosexuality.
