What is the appropriate response to an article by a secular infidel who describes Islam as cancer and calls for fighting it, and what are your efforts to close down the website and inform the questioner of the response?

We have reviewed the published article and found its author to utter disbelief without compunction. This is always his method: mockery of religion and its constants, and ridicule of those who adhere to it. Not even the Messenger, may Allah's prayers and peace be upon him and his Household, and his Companions, were safe from his insolence.
