I don't know any "Christians" who practice those things.. and pointing to the evil that satan works in a nation does not defeat the good that God has wrought in His People.The legal system was not drawn from The two commands. They were drawn from a whole lot of code that has been with men and for men.
And what people?
The people that savaged the aboriginal populations?
The people that enslaved Africans?
The people that kept women as second class citizens?
The people that kept the non-land holding citizen from equal treatment?
How are ANY of these things even close to keeping the second command?
If you cannot follow the second, you cannot follow the first. If you do not follow the Commands of The King
you are NOT WITH The king.
The fruits are NOT there. US not Christian. Just another worldly nation.
