Why American and European people hate Arabs and see them as enemies?

The western media tends to paint Arabs as uncultured and somewhat uncivilised. There's an image of Arabs as being violent, authoritarian fundamentalists and extremely patriarchal. Their laws are based on religious intolerance, making them bigoted, and are designed to keep women as second class citizens under the strict control of males and to criminalise the LGBT community. They are seen to worship a false God and despite their vast wealth they lack class and breeding and promote Islamic terrorism.
I think that covers most of it.
