This whole religious argumentation is pure straw man. Whether people of religion approve or disapprove of homosexuality is irrelevant, immaterial and beside the point when it comes to natural or civil rights.

Human Beings are endowed at conception with unalienable, natural rights. These rights are universally applicable independent of sexual orientation. I have no more right to be heterosexual, as a homosexual has to be homosexual; sexual orientation is irrelevant to rights. To demand rights because you are homosexual is about as idiotic as heterosexuals demanding rights based upon their sexuality.

Given this, it is not the natural rights endowed at creation homosexuals seek as they already possess those, what they seek is government granted privileges "special rights" and the use of government force as a means to impose those privileges upon heterosexuals, thus denying them their natural right to liberty.

Natural rights are expressed in America as the right to life, the right to liberty and the right to pursue happiness. Note: Happiness is not a given but you do have the right to pursue it.

Governments are instituted by man to protect and perserve those unalienable, natural rights within a socital environment. This protection takes form as civil rights as expressed within the Bill of Rights:

Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

Amendment II

A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.

Amendment III

No soldier shall, in time of peace be quartered in any house, without the consent of the owner, nor in time of war, but in a manner to be prescribed by law.

Amendment IV

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Amendment V

No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a grand jury, except in cases arising in the land or naval forces, or in the militia, when in actual service in time of war or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

Amendment VI

In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defense.

Amendment VII

In suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise reexamined in any court of the United States, than according to the rules of the common law.

Amendment VIII

Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.

Amendment IX

The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

Amendment X

The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.

--------------------------------------------------------

These civil rights only protected individuals from Federal Government encroachment but were extended to include encroachment by state's government with the addition of the 14th Amendment to our Constitution.

Other civil rights retained by the people are: The right to equal protection of your natural rights under the law. The right to vote. And the right to access public buildings, parks and throughfares held in common by the people through government.

That's about it. Anything above that are privileges granted by government at the expense of someone else’s liberty to which you do not possess the right to infringe. If homosexuals choose to attempt to gain privilages through the use of government force, others retain the right to reject that attempt to usurp individual natural and civil rights, civically, by vote.

Also: The "Nature verses Nurture" argument is also a straw man with the comments attributed to Rita Cotterly being the most egregious. But that another subject for another time.
