The concept of Islamophobia as formulated by Runnymede was also criticized by professor Fred Halliday on several levels. He writes that the target of hostility in the modern era is not Islam and its tenets as much as it is Muslims, suggesting that a more accurate term would be "Anti-Muslimism". He also states that strains and types of prejudice against Islam and Muslims vary across different nations and cultures, which is not recognized in the Runnymede analysis, which was specifically about Muslims in Britain. Poole responds that many Islamophobic discourses attack what they perceive to be Islam's tenets, while Miles and Brown write that Islamophobia is usually based upon negative stereotypes about Islam which are then translated into attacks on Muslims. They also argue that "the existence of different 'Islamophobias' does not invalidate the concept of Islamophobia any more than the existence of different racisms invalidates the concept of racism."
