Some of the most dangerous ideals in history came from "just books", i.e. Marxism, Satanism, Mulsim, etc.
Are those "ideals" any more dangerous than the ones found the bible? The so-called "good book"? Full of such undangerous "ideals" as...
-Suffer not a witch to live
-If your brother, son, daughter, wife, or friend tries to get you to worship another god, "thou shalt surely kill him, thine hand shall be first upon him to put him to death
-Give no thought to tomorrow.
-Visit the iniquity of the fathers upon the children unto the third and fourth generation
-And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people.
-For every one that curseth his father or his mother shall surely be put to death.
-The children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they begat in your land: and they shall be your possession.
-This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard. And all the men of his city shall stone him with stones, that he die so shalt thou put evil away from among you; and all Israel shall hear, and fear.
-If any man come to me (Jesus), and hate not his father, and mother, and wife, and children,and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
And those are just the ones i can think of off the top of my head. What do you think the list will look like if I were to pick out every single "dangerous ideal" in your holy book?
