If he is a Moslem, then it is haram for him to consider himself American. Islam cannot be modified.

“......Islamists make appeals to diversity and tolerance, adopting soft-focus language to disarm Americans emotionally, at least those who want to believe. They seek to suspend all critical thought about Islam, using free speech, so-called, to win the culture wars, with grave implications for national security. The American devotion to religious pluralism gives them a political wedge.
I have been tracking this cultural assault in U.S. elementary and high school textbooks for a decade or more. I remain puzzled and shocked that progressive Americans ardently fail to acknowledge Islam for what it is and what it seeks.
Keep in mind. Many Islamists reject freedom of speech and religion, thinking of non-Muslims as infidels without human rights. They openly subjugate women, excluding them from governance, worship or thought. They think homosexuals should perish. They by and large approve of terror and believe that apostates deserve to die.
Perhaps Islam is the religion of peace, and Ben Affleck and Gen. Casey will certainly assure us of that. Unfortunately, many dolts will listen to them.
But peace means submission to Islamic rule and Islamic law. The absence of sharia law is the absence of peace. With God on its side, Islam wages eternal global war against territories under non-Islamic rule. Until they cease to exist or submit to forces loyal to Allah and his Prophet, the holy struggle will endure. And so will the lethal, ghastly incidents being splashed across the news.”
