With the anniversary of Auschwitz having just past and the stories of the sins committed by the Germans and seeing America starting down that same path, I cannot help but wonder where the divide between salvation and damnation was and is.
I think there is much exaggeration in your post.
Do you hear in America a group of people to be called as subhuman parasites that are dangerous conspirators against humanity? Is there a call to wanton violence toward such a group of people and their property? when some random guy would seriously injure or even kill someone of this group of people, will he have immunity for his action? Do you see a revisionism of history and of the Bible to purge anything that could be favorable to such a group of people? And is the majority of the media promoting such views as above?
So, I believe there is a much longer way for America with its immigration politic to go the same path as Nazi Germany, as you think! The real danger comes when a nation rejects God and His laws, and put an ideology or a person above everything. The confessing church of Germany was heavily persecuted by Nazi Germany, because they refuse to let anything else have a greater authority than God's Word; yes they refused to grant such an authority to the Fuhrer and his ideology.
The root of the evil of Nazi Germany was actually its claim to be above everything, including God and His Word. The most evil people are the people who don't believe that they have to answer to God for their actions. Many secular nations (including modern Germany) mention a responsibility toward God in their constitution, although it goes against their secular philosophy. They however see that as a necessity to prevent WWII crimes to happen again!
Finally, to know whether or not America is going down the path of Nazi Germany, we need to look at the right indicators: Can christians “
lead a quiet and peaceable life in all godliness and honesty” (1 Tim. 2:2). Or is there an ideology that doesn't want to let them live in godliness and honesty as the Bible teach us, but wanta to force its ungodly view on them? Can christians in America peacefully live according to their faith and conscience? Or does an ideology claim a higher authority than their christian faith? Is there an ideology that wants to remove God from constitution, schools, etc? That's the right questions to ask oneself!
