Even though the state should be involved with very little, they do have the right and authority to help govern society morally. Theft, murder vs. self-defense, and many other crimes are moral issues and judged by intent.
They are crimes not for arbitrary reasons, but because they infringe on the rights of others. Being homosexual does not infringe on anyone's rights, nor does being a homosexual couple with custody of a child. If no rights have been infringed upon, then no crime has been committed. A right, by definition, cannot imply an obligation on someone else (i.e. you have a right to your life, but I don't have an obligation to sustain your life).
Being raised by homosexuals and being in that culture DOES raise your risk of becoming mentally unstable by becoming a homosexual.
Homosexuality is unnatural. That's not a debate.
It certainly is a debate. I disagree with your presentation of the facts.. is that not the foundation of a debate?
Quite the contrary, homosexuality is very natural, defined by the fact that it exists in nature among non-human animals:

If homosexuality was natural they wouldn't need adoption for those body parts which are intrinsically ordered for reproduction.
Your statement is far too vague. If homosexuality were a method of reproduction that required artificial assistance, then it could be classified as an unnatural way to reproduce. Artificial insemination is also not a natural method of reproduction; should we ban that? Homosexuality is not a method of reproduction and needs no artificial assistance to occur -- It occurs in nature, and is therefore natural.
Homosexuality is intrinsically disordered. The intrinsic nature of man or woman produces nothing by acts of same-sex attraction except by pleasure, which is commensurate with chewing on food you enjoy and never swallowing.
Should we then ban that also? Is the purpose of action defined as "legal" that it must have some productive benefit to society? On the contrary, that's socialism, not freedom. Freedom is me (and everyone else) being able to do whatever we want, regardless of the societal benefits, so long as we don't infringe on the rights of others.
Both eating and sex produces the survival of the species, one individually, one societal. Any threat to that prolongation is condemnable by every government and should be punishable.
My wife and I have no intention of having children, but we very much enjoy sex. It seems that we threaten the prolongation of the species and are deserving of punishment. Is that your conclusion as well?
I am not an anarchist, I believe government has its place and one of them is adoption. Children without parents have a lack of sovereign protection that their parents provide them and that a private institution cannot provide them.
I agree that children should have parents. I don't know how you then make the leap to "government should be involved in adoption."
The idea comes from psychological reports stating that a child is best raised in a family with both the mother and father. The interaction the mother and father have with the child provides a healthy environment needed for the child and the various hormones given off by the father and mother effect a child's biological and mental development.
Link please?
My (very quick) research on the topic shows up articles like
this,
this, and
this, which indicate that there are no known negative effects, or that studies over the past few decades are inconclusive. Any negative effects would be purely speculative.
One of the articles mentioned above says that children raised in homosexual households may be more prone to experiment with homosexual behavior. Unless you're arguing that there's something inherently wrong with being homosexual, this is not a negative.
