Anti-muslim views were far from new either - especially in the US. Glimpses of this can be found in some films and tv programs from decades prior - cliched 'middle eastern terrorists' who would be both mocked and hated, and who would be very loosely based on earlier 'famous acts of terrorism'. Even without 24/7 news the likes of the Beirut barracks bombing was something to be used and etched in the minds of the public. And the long Iran-Iraq war and the caricatures of Iran's leaders post-revolution. The outcry over fatwa's against Salman Rushdie.
It was the Shi'tes I remember as being always on the news back in the Eighties - Iran and Lebanon.
Afghan Islamists were still the good guys then
