Satanists love the KJV...to bash it.

First of all, the things you listed are found in EVERY BV, and not just in the KJV. And the KJV has been used by both cults and devout Christians alike, same as any other valid Bible version.

As for your specifics:

God has always equated idol worship with whoredom. And some things which are now considered vulgar were everyday talk 'back in the day'. He is hectoring Israel and Judah for worshipping the gods of nearby nations, especially larger nations who have conquered them, such as Egypt, Assyria, & later Babylon. He uses descriptive language to make sure His target readership "got the message".

First, dried dung was often used as fuel in those treeless areas to which Israel was to be exiled. However, using HUMAN dung for cooking fuel would ceremonially defile the food in God's sight. And you're misplacing the emphasis of Ezekiel 4:12. What was to be done in their sight was the EATING OF THE DEFILED BREAD, not "using the facilities". God is emphasizing that if Israel continues to sin, she will be reduced to desperate means to obtain food, among other punishments.

The "dung upon the faces" is God's reminder to israel that He's gonna punish them most severely for their continued sin. And Israel's enemies could well have carried out that dung facial literally.

2 Samuel 12:11 is about the fact that when one king wished to show supreme hatred and contempt for another king, he took that king's wives and concubines & lay with each one of them, as Absalom did with a group of David's wives, thus polluting them in the eyes of that king. At the time of that writing, there were different views of monogamy, adultery, & surrogate motherhood.(Abraham, Sarah, Hagar, Ishmael)Here, God is again warning of most severe punishment for Israel if she continues to sin.

Abortion in Numbers 5? Not hardly. Evidently, if the woman is guilty, God sends some kinda illness upon her which causes her belly to swell & her thigh to rot. That's hardly the aftermath of an abortion. In fact, if she's innocent, the Scripture says SHE SHALL CONCEIVE.

Crude-sounding or not, these are some of the warnings, curses, and ceremonies which God gave Israel. Now, JESUS is Savior, High Priest, and Judge Advocate for Israel and all the rest of mankind. He FULFILLED, not erased, every sacrificial aspect of the law, so that the adulterous person and the idol-worshipper answers to HIM, rather than to other men, if he/she doesn't come to Him in belief, repentance, & submission.
