I would not lay down my life to protect things like gay marriage or abortion on demand, or the new bathroom policies. And the government is becoming more hostile to Christians.
America is dying and I would not fight to keep the corpse alive.
There are Churches that are now flying the Christian flag over the American flag, and pastors are counseling young Christian men that joining the military is really not an option because of what the government is doing.
Christ himself said don't throw your pearls before swine.
I would also encourage my son not to enter the military at this time. Too much is going on right now with All Branches. My son got out because of the changes he saw and had to deal with. I also know an 18 yo that just got sworn into the Navy. He is a 18 yo Hispanic that really has no choices in order to better his life. He will go in for 4 years hoping to see the world. I pray he knows what he is doing. His mother was not happy, but she supported his choice. For some, this is the only way out of the ghetto.
