what is an average American perception of a Christian American and also that of a Muslim and Arab America?
I'm not sure there is an "average American perception." People's opinions vary widely within the country. Some people are very racist, and others welcome diversity.

The idea that there is an "average American perception" discredits too many Americans. Americans of all nationalities express opinions that vary widely because of our democratic system. As with every country in our universe, one will encounter those who may be racist and one will encounter those who welcome diversity.
