The strange case of William Lines

The weekend Australian had an extract from William Line's new book in which he complains about environmentalists support for indigenous land claims accusing them of racial thinking. It seems The Australian will use any argument against indigenous people today, but it is curious they use Lines whose first book Taming the Great South Land blamed environmental decline in Australia on evil white males inspired by the Enlightenment and Adam Smith etc. etc. even the CIA rates a mention in this green armband tome. Is it such a preachy and dogmatic book that I don't use it as an academic resource.
