Why is Hong Kong screaming about the indecency of the Bible and wanting it banned it from the children?
You need to read the news reports more carefully. Hong Kong as a government or society is not calling the Bible indecent. There is an agency in the Hong Kong government who has reported receiving numerous (about 1,500 the report said) complaints that the Bible ought to be labeled for adults only because it mentions things like murders, rapes, incest, and other sinful behaviors.
Most people believe it is a hoax or a campaign by radicals trying to bring pressure on China for censoring material. It is basically the idea that if I can't publish anything I want, then no one else should be allowed to publish either. There is a particular website that is being cited as the source of this campaign, urging people to complain to the agency in charge of labeling books as decent or not.
Of course, the problem being ignored is that the same criteria would ban all newspapers because they report that crimes exist. It would ban all Bibles and religious papers because they mention crimes in order to condemn the sins. What these silly people with an agenda are willfully ignoring is whether the Bible promotes or condemns the actions. They don't care. They want to have full rights to publish anything they desire. It is the writings of Paul, Peter said, "which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures" (II Peter 3:16).
