Hm, as human being I found this article disturbing and very immature. There is no "hard" themes that shouldn't be discussed but in way how these two authors done it, it is completely insensitive and obviously crossing many "ethical" standards. So in some way it is ridiculous to see incompetent people discussing such matter and it is even more crazy to see unethical text (if I may say so) about ethics and worth of human life.
No wonder that authors have been living in nightmare after publishing such "work".
Here is article about Dr. Francesca Minerva receiving death threats after co-writing this article:http://www.ibtimes.com/dr-francesca-mine...-threats-419638
