Islam is an ideology. Rejection of an ideology cannot be classified as phobia. To call the opponents of an ideology phobic is a fallacy. All ideologies have their critics and opponents but we do not hear Christians calling the critics of Christianity Christianophobe, communists calling their critics communitophobe or Hindus calling theirs hinduphobe. The term "Islamophobia" is both technically and logically incorrect and misleading.
Correct. Muslims in general can't handle any criticism of Islam. Small differences in beliefs and rituals within Muslim communities are enough to bring on discrimination and general rudeness.
Take for example the experience of the Ahmadiyya sect in Pakistan. The government and the majority public of Pakistan don't consider the Ahmadis to be Muslims. Those who call themselves Ahmadis can't call their place of worship a mosque. Pakistani passport applications and other types of documents specifically ask whether one is a Ahmadi or not which makes public discrimination easier.
Apostates by definition have rejected the faith and are thus treated with utter revulsion. The Afghanis openly called for the death of a Muslim apostate last March. Recently, an Iranian convert to Christianity was put in jail.
Yet, somehow, merely criticizing Islamic law and the atrocious behavior of the Prophet Muhammed is now "Islamophobic" and on par with racism and antisemitism. Instead of the physical bullying or death that accompanies an unfavorable judgment of Islam in the Muslim world, we in the West get rhetorical thuggery.
