"When fascism comes to America, it will be wrapped in the flag and carrying the cross."
The gut-pulling emotional power of both nationalism and our faith is great - combining the two must be done carefully, if at all. How easy would it be to forego our humbleness in favor of arrogance derived from being convinced we're right? Where did Jesus display an arrogant attitude? Even under pain of death, with no friends, He still accepted the free will of the people to not accept Him.
Our Constitution allows for debate, and God is big enough to accept our questions. We must not force conformity by handling dissent with accusations that one isn't patriotic or religious enough.
Nazism thrived under those types of conditions - we must maintain the integrity of our Constitution and the protections they provide for all Americans to prevent national discourse from diving down that slippery slope.
