Surely the mother of the girl must havec had many bad experience with muslim people, from here is the hate. Personally I know many muslim people (how can I not here? :D) and most of them are nice.
But of course on the other hand there are also very bad people between them. Ok, there are bad people from all religion actually. But some muslim (I said some, so who reads it doesn't one of them, please don't take it personally) tend to be very fanatic, which is not common in other religions. For example the suicide bombers.
