Do you seriously believe the Leftist lies about January 6? The only thing that was evident was agents provocateurs from the FBI making sure that a peaceful demonstration turned into a riot. Calling it an "insurrection" was a deliberate falsehood, and Liz Cheney and her gang of liars have all been exposed.
Now the terms "Christian Nationalism", "Christian Nazis", "Domestic Terrorists", "White Supremacists" etc are all being used by the American Communist/Fascist/Racist Party to smear conservative, law-abiding citizens, and promote lawless actors like BLM , Antifa, and FBI as the "good guys".
Whether you like it or not, Christianity and Christian principles have undergirded the polity of America until very recently. Here is what the Pledge of Allegiance says:
"I pledge allegiance to the flag of the United States of America; and to the Republic for which it stands, one Nation under God, indivisible, with liberty and justice for all.
The Communists who now run the country hate God, hate America, hate Christians, hate conservatives, and hate everything that is right, good, and moral. So Christian Nationalism is not necessarily a bad thing (although I have no connection with it).
