It’s an insult to the intelligence of Muslims, frankly to all of us, to keep claiming that terrorism today is not linked to Muslim migration, as the ASIO Director General, Duncan Lewis did, in a Senate hearing at the end of last week. As several other public figures have in the past, not least the Prime Minister, the scramble away from this hard fact on the grounds of appeasing the Muslim community is not only transparent and disingenuous, it is rather infantile.
