Never heard of the Suez Crisis?
Sure, so are you arguing that the suspicion of Muslims in the United Kingdom comes from the Suez Crisis? Were there mass movements in the United Kingdom against Islam during the 1950's and 1960's?
Hell, even after the fatwah against Salman Rushdie and attacks on bookstores which stocked his books, there wasn't any kind of movement against Islam that I can recall.
How many Muslims were there in the UK (Britain specifically) to build mass movements against during the 50s and 60s? Google is telling me that just 12 years ago, the UK's minority population has tripled from ~12% to ~38%. I'd be surprised if Britain wasn't 98% white European in the 1950s.
What was the nature of the average British person's exposure to the Arab world via the Suez Crisis?
State-owned media, the press, etc.
There was a certain point that Muslims started to be viewed suspiciously, it wasn't like this always in the west, especially in the United Kingdom where Omar Sharif for example was one of the most beloved "celebrities" around.
dumbass brits will now have a government divided right down the middle and fuckall will get done. congratulations
Seriously? One Muslim celebrity is evidence of acceptance for you?
And yes, it has been like this for a long time in the West. The stereotypical image of the villainous Muslim has long been standard fare in Western narratives. Thomas Pynchon pokes fun at this as early as 1961, in his short story "Under the Rose," which is set in Egypt in 1899. Muslims are represented as being treacherous and traitorous, and as easily bought. He wasn't just plucking these representations out of the air, he was commenting on normative depictions of Muslims in popular fiction.
