God: "Have ye not read, that he which made them at the beginning made them male and female. And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?"
God created heterosexuality. Reprobate man changed the truth of God into a lie. Because of this God gave them over to vile affections...without understanding, convenant-breakers, without natural affection, implacable, unmerciful; who knowing the judgment of God, that they which practice such things are worthy of death, not only do the same, but have pleasure in them that do them." (Romans 1:18ff,32)
Praeger is wrong and miopic. The ancient world was originally hetero, but sinful man corrupted God's design. The filthy Romans, Greeks, Jews, etc. all fell into these vile sins. God's law sheds the light of truth on this abominable behavior. Men know it. Even the most reprobate will not brook criticism of their filthy conduct. They use the law to not only force it upon us, but require us to enshrine it, giving it a place of honor. Alcoholics behave this way, looking for affirmation. Never.
