That's simply not true. Most Arab-Americans don't vote Republican. And the vast majority of Muslim Americans don't either. I will show you some polling data later (I'm about to go to bed). Look up the Pew Research Center's data.
That wasn't a report, just a video (that showed nothing anyway). More importantly, Dearborn is a very divided city. The Arab/Muslim dominated eastern half are very, very democratic (Obama got 80%+ vote in eastern Dearborn). The western half is mostly non-Arab, wealthier, and somewhat Republican-leaning. What happened was that Arabs in Dearborn voted for Bernie in the Democratic Primary because they are overwhelmingly Democratic. The non-Arabs voted for Trump in the Republican Primary.
Arabs only make up about 30% of Dearborn's population:
"The city's population includes 40,000 Arab Americans.[21] Arab Americans own many shops and businesses, offering services in both English and Arabic.[22] Per the 2000 census, Arab Americans totaled 29,181 or 29.85% of Dearborn's population; many are from families who have been in the city since the early 20th century."

Anecdotal evidence varies. I live here, and know of no Muslims supporting Trump. Everyone's scared to death of him. I've even heard conservative imams go so far as to ask people not to vote for him when giving Khutbahs. My family that live in other states report the same.
Muslim-Americans are among the most Democratic-leaning groups in the country. That's a fact. All polling and party affiliation show this. You're crazy if you think that most Muslim-Americans voted for Trump. Come and visit sometime and you will see. Very, very few did.
This is the only part of your statement that I have a problem with. You're crazy of you think that most of his 58 million+ supporters are racist. Some of these people voted for Obama too. There is no exit-polling data to back up your outrageous claim, because it's false. You are the one in denial here.
