Not sure racism is the proper term, although there are Americans who are racist and hate any group coming over, and have killed Sikhs thinking they were Muslims. Islam is only 1400 years old, many of the people who are Muslims today (many forced into that religion historically like Christians during the Inquisition) have ancestors who practiced Zoroastrianism. And there are followers of that religion today who are persecuted in Iran and other countries where it is still practiced. In fact ISIS is destroying ancient sites exemplifying the heritage and culture of their own race. Even if other Muslims didn't destroy those sites, they are considered the achievements of infidels. The "cradle of civilization" was just populated with mere infidels.
The 3 monotheistic religions at their very best, are divisive and devalue all people who are not followers of their same faith. And there are death penalties in countries who practice Sharia law for apostasy - which just means deciding not to follow Islam any longer. This is all outside of terrorism, just the rule of law most Muslims believe the world should be governed by.
These ideas are dangerous and always have been. But before oil and wealth in the Middle East it didn't affect anyone in the western world, and thus no one cared. It took centuries for the Christian religion to splinter into so many opposing groups until people finally realized that religion and government had to be separated, and differences had to be respected. Islam still needs several generations of apostates and blasphemers in order for people to let go of an idea that there is one correct religion belief that can be legislated. Unless the people you're talking about start speaking up and being heard, it'll never happen. Islam needs a 95 theses nailed to the Wittenberg door.
