Thank you, Mr. Sweet.
Anti-Semitism is a very interesting term, because anti-Semitism is not the same as anti-Judaism. The Semitic races, strictly speaking, include both Jews and Arabs, and Muslims and Jews, but it is true that over quite a long time, the term has acquired a conventional meaning that is widely understood. People don't use “anti-Semitism” to talk about anyone other than Jews, if that is the direction of the offending behaviour.
Islamophobia is a relatively new term. In fact the term—referring to an irrational fear or phobia—already discredits anything that might be negatively construed, or proposes that there might be rational fears, so it is a problematic term.
It could be that 150 years from now everybody will know what it means, in the same way as anti-Semitism is understood. At the moment it's not; therefore, both my fellow witnesses here suggest that it could be misunderstood.
