JR believes mosaic law should be applied under current circumstances
Wrong.
The Mosaic Law was for Israel, and no other nation.
What I want is for our nations laws to reflect God's laws, as Israel's Mosaic Law did. I am a theonomist.
which is actually even uglier.
Only for criminals, and only in a good way.
That would be an ongoing society where government employees must routinely kill and maim people for relatively minor offences.
Again, wrong.
The government only puts people to death for capital crimes, which are not minor offenses to begin with, and a punishment of maiming is to match what happened to the victim, for example, as described earlier to PureX, if during the commission of a theft, you cut someone's hand off, then your hand should be cut off as a punishment. In addition to paying restitution for the theft.
Or, as the Bible puts it:
"Life shall be for life, fracture for fracture, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, stripe for stripe."
This isn't Islam, where you cut off the hand of a thief. That's unjust, not to mention cruel.
A vulgar perpetual dystopia unmatched by a couple generations of harsh repopulating.
False.
Also, God said to be fruitful and multiply, so there's nothing wrong with repopulating, or populating, for that matter. No idea what you mean by "harsh repopulating" though...
