Looks like Amash has a positive political rating with the Arab-American Institute:

My great-grandparents were Maronite Catholics from Lebanon, and I am very familiar with Arab Christians. It is almost unheard of for Arab Christians to defend Iranian Muslims, particularly Islamist nutjobs like Ahmadinejad who finance Hezbollah, a terrorist “political party” responsible for the death of countless Christians in the Middle East. That Justin Amash sees fit to lionize a dangerous, anti-American buffoon like Ahmadinejad, and to chastize a Republican Senator for making a mild joke comparing Ahmadinejad to a monkey (when, in truth, it is more of an insult for the monkey) makes it clear that Amash is even more anti-American than your average Ron Paul cultist.
Justin Amash needs to be defeated in the 2014 GOP primary.
