First of all, the meaning is vague. Second, as I have mentioned, the term “Islamophobia” was coined after 9/11—you don't have to take my word for it; it's all electronically available—by an operative of the Muslim Brotherhood, who actually said, and is quoted as having said, that they would throw this term out there so that there is no questioning, criticism, or any kind of discussion about Islam and Muslims.
I believe that, to a great extent, they have succeeded. It's a new term. It didn't exist 30 years ago. I had never heard of it until 9/11, and it was put out there to effectively stem any kind of critical debate or discussion.
