There is a lot of harsh persecution of Christians around the globe, but the worst that American Christians have only been dealing with, is people saying mean things or being shadow banned on social media.  

I was recently reading that the US government and DOJ are keeping track of everyone who buys a Bible or Christian literature and storing it in a criminal database.  I think American Christians are about to start experiencing the same kinds of persecution that many of their international brothers and sisters in Christ have been experiencing for a long time and they are going to be shocked.  Sadly, I think a lot of Americans, who consider themselves Christians, are going to drift away when the going gets rough.  We will see.
