Soldiers of nations are duty-bound, first and foremost, to God and the Holy Bible.
This means that the Law of God trumps any Oath of Allegiance, national constitution, loyalties, military code, direct order from the commanding officer, secret ops, national security directive, or any laws, military or civilian.
Both the New Testament and the Old Testament fanatically condemns homosexuality.
In the New Testament, St. Paul, who lived in a nation that was aggressively tolerant of homosexuality, was emphatically against homosexuality and preached against homosexuality. Many of the Christian disciples were killed by the Roman democracy by official, due process of law, because they were charged with hate crimes for opposing homosexuality and other religions.
Unfortunately, the United States Supreme Court crossed the red line, when it made the decision to force/coerce all American citizens to submit to pro-homosexuality laws.
Thus, the United States government should expect that there are efforts for regime change among military personnel, the secret service, CIA agents, FBI agents, Homeland Security Agents, and ordinary US citizens.
The majority of Americans are Christians, and we have a current situation in which a very small minority is forcing their will and morality on the majority of Americans who submit to Christ and the Holy Bible.
Thus, it should be expected that there will be coup-de-tat attempts in the coming years.
Right now, everyone is waiting for the 2016 election. Many people are willing to give that a chance in the hopes that gay marriage laws will be overturned by peaceful means.
But after 2016, if gay marriage laws are not overturned, the United States government should expect coup-de-tat attempts to bring about regime change.
The majority of Americans do not want a pro-gay America. So, this is just expected. Simple logic.
