It is easy to take parts of any holy book and make it sound like the most inhuman book ever written.QFT.
The qualification is telling. It's easy to take parts of the three Abrahamic holy books and make them sound inhuman because they are in fact inhuman. One does not have to quote-mine, take statements out of context or otherwise misrepresent the plain meaning of the text to "make" these holy books sound inhuman: all you have to do is read them.
Try taking the Humanist Manifestos and make them sound inhuman. How about the Declaration of Independence or the Universal Declaration of Human Rights. Not so easy, eh? If you could do it at all, you'd have to quote-mine like a cretinist on crack.
If it's easy to make your book sound inhuman, perhaps you should re-think its holiness.
