The antispécisme example is presented as a current of deep ecology (deep ecology), while the mere reading of a definition (Wikipedia), or better a reference book on the subject (Animal Liberation) allows to understand that these two currents do not have much in common.
Another example is to alert us to the dangers of granting rights to animals, the author extensively discusses Hitler and his supposed sympathy towards animals. But this sympathy is found not only unfounded (see work cited below), but does not show anything (should we not use motorways because Hitler was involved in their development?).
If you hold still about getting this book, see as Luc Ferry or restoring order which, besides severe criticism of this essay presents essential information for better understanding.
