Your analysis is very superficial. Submitting to the laws of the land is first priority in a Christian belief. God himself established governments from the beginning of the world, and the US government most of all is inspired of God. If you go about obeying the law of God and do all you can to obey, but are constrained by laws or governments beyond your control, the Lord will not require it more of you.
To put it another way. All the innocent children that died in communist countries or otherwise had no knowledge of Christ and his teachings, they will not be punished. Only the most evil of persons would think a child that dies before the age of accountability needs to be cleansed of sin, and the same goes for persons with mental handicaps and even the many who have died without knowledge of the gospel.
AZnd right there is your error:
So, if the USA decides that Homosexuals have a right to be Boy Scout Leaders, and got a law passed to that effect, would you guys then submit your children to camping with them?
