Pertaining to the Bible:
The intent of the Ten Commandments was a code of Jewish law, so in other words, "Thou shall not kill Jews". Kill all the gentiles you want.
The story of Abraham being told by god to kill his son.
The story of Sodom and Gomorrah.
The story of the conquest of the Holy Land by Moses.
The 7 plagues.
The story of Noah and the flood.
The story of Job.
The Book of Leviticus.
The story of the Crucifixion.
Religion a creation of Satan? OK, I don't believe in Satan, but this seems to hold less water than the theories presented in the movie Loose Change.
#1. The Nation of Israel was comprised of the descendents of the 12 sons of Israel (Jacob), not just the tribe of Judah (Jews). The law also included any "strangers or sojourners" in their midst.
"The same law shall apply to the native as to the stranger who sojourns among you." - Exodus 12:49
As for the assembly, there shall be one statute for you and for the alien who sojourns with you, a perpetual statute throughout your generations; as you are, so shall the alien be before the LORD. - Numbers 15:15
'There shall be one standard for you; it shall be for the stranger as well as the native, for I am the LORD your God.' - Leviticus 24:22
Your mentioning of the story of Abraham and Isaac leads me to believe you read a book full of "issues with the Bible", because at more than a cursory glance it was obvious that Abraham had faith that Isaac wouldn't be offered:
Gen 22:8 And Abraham said, God will provide himself the lamb for a burnt-offering, my son. So they went both of them together.
and what happened?
Gen 22:12 And he said, Lay not thy hand upon the lad, neither do thou anything unto him. For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me.
Gen 22:13 And Abraham lifted up his eyes, and looked, and behold, behind him a ram caught in the thicket by his horns. And Abraham went and took the ram, and offered him up for a burnt-offering in the stead of his son.
The story of Sodom and Gomorrah: What? You have a city full of (at least guys) who were going to break into a guys house to rape a couple of strangers, and the occupant of the house for not opening the door. There were not "ten rightous people" to be found in the whole city, even being given a "head start" with some family members of Abraham.
The story of the Flood is somewhat similar in this regard. Especially considering when reading passages like
en 6:2 that the sons of God saw the daughters of men that they were fair; and they took them wives of all that they chose.
Gen 6:3 And Jehovah said, My spirit shall not strive with man for ever, for that he also is flesh: yet shall his days be a hundred and twenty years.
Gen 6:4 The Nephilim were in the earth in those days, and also after that, when the sons of God came unto the daughters of men, and they bare children to them: the same were the mighty men that were of old, the men of renown.
Gen 6:5 And Jehovah saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
in light of some of the apocryphal works(The book of Enoch for example). The Nephilim were "demonspawn", to put it in plain English.
The story of Job was actually Satan doing all he did to Job. God just didn't step in. However, at the end,
Job 42:10 And Jehovah turned the captivity of Job, when he prayed for his friends: and Jehovah gave Job twice as much as he had before.
The plagues fall under the same line as SaG and the Flood. It was supernatural judgement.
God is either God, or he doesn't exist/isn't God/ this story didn't happen (not to mention any of the other supernatural event stories). If he is God, does he not have a right to act as judge? If he isn't, it's all a lie anyway so it doesn't matter.
I don't follow your line of thinking at all on the death of Messiah or Leviticus. That's pretty vague.
The one point I do understand is an "outside" view of the invasion of the promised land. Couple of points:
1. God already gave it to Abraham and his descendents, prior to many of those people moving in/settling.
2. Who were "those people"?
Num 13:28 Howbeit the people that dwell in the land are strong, and the cities are fortified, and very great: and moreover we saw the children of Anak there.
Nephilim who were not all destroyed in the Flood. Prior to reaching the Jordan they had already killed a Rephaite (Nephilim) king, Og the King of Bashan. While you are horrified by the thought of the possibility of thinking about sacrificing a child re:Isaac, the inhabitants of Canaan were devout child sacrificers.

Regarding the rules regarding beards, lets look at the context:
Lev 19:26 Ye shall not eat anything with the blood: neither shall ye use enchantments, nor practise augury.
Lev 19:27 Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard.
Lev 19:28 Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am Jehovah.
Lev 19:29 Profane not thy daughter, to make her a harlot; lest the land fall to whoredom, and the land become full of wickedness.
Lev 19:30 Ye shall keep my sabbaths, and reverence my sanctuary; I am Jehovah.
Lev 19:31 Turn ye not unto them that have familiar spirits, nor unto the wizards; seek them not out, to be defiled by them: I am Jehovah your God.
These were all specific commandments regarding the ways that the Egyptians and other surrounding cultures "worshipped" their gods. Through incantations, temple prostitution, eating/drinking of blood, and considering context, certain shaping of the beard and cutting/tattooing. Coming from a few hundred years of only knowing about those ways to worship, the people had to be instructed differently.
