That's simply false. There are plenty of examples, but one is all that's necessary to prove the point. In Deuteronomy 13:12-17 are instructions to burn down any city and kill all the inhabitants if they worship a different god. Seems pretty unkind to me, as are many of the prescriptions for correct behaviour in Leviticus and Deuteronomy. You can be killed for wearing clothes made of two different kinds of fibers, planting two different crops in the same field, working on the Sabbath, cutting your hair, and a whole lot of other things.
I'm not sure why you are applying rules of 'social behavior' that were given to OT Israel as having any sort of meaning of what instruction Gentile Christians are under. If you were to apply those rules then the mere thought of doing any of those things would be enough to find a person guilty.
M't:5:28:
But I say unto you,
That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
That would also cover any of the other 10 commandments. While some things were 'relaxed' for the Gentiles, like the things given in the OT, even though some make perfect sense in hygiene still today, other things, like obedience to the 'law' were hardened so that adherence is simply impossible.
And if you're going to argue that Jesus brought a new set of rules and those old ones no longer apply, I would point you to Matthew 5:18-19, which quite clearly says the old rules apply.
I'm quite sure it was the 10 commandments alone that was being referenced, Romans 13:9 & James 2:8-11
And yes, I know you can also find citations that say they don't.
Like these? (and really these are just a few single verses)
Ro:12:17: Recompense to no man evil for evil. Provide things honest in the sight of all men.
Ro:12:18: If it be possible, as much as lieth in you, live peaceably with all men.
1Th:3:12: And the Lord make you to increase and abound in love one toward another, and toward all men, even as we do toward you:
1Th:5:14: Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men.
1Th:5:15: See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men.
2Tm:2:24: And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient,
Ti:3:2: To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men.
Not directly perhaps, though I think the previous example applies here as well; a city where a different god is worshiped can certainly be seen as having rejected the Gospel.
Being as the Gospel of Christ wasn't in existence back then how could it be rejected.
God gave direction that 'we' should listen to what Jesus said, that would include rules of conduct towards all men.
M't:17:5:
While he yet spake,
behold,
a bright cloud overshadowed them:
and behold a voice out of the cloud,
which said,
This is my beloved Son,
in whom I am well pleased;
hear ye him.
The New Testament also allows plenty of latitude for interpreting things that way. There's a nice verse in 2 Timothy 2:19 that was used by the inquisition to justify killing people just suspected of heresy, and letting god sort it out.
Well they should have read to the end of the chapter, the verse is already posted above, 2Tm:2:24.
"The Lord knoweth them that are his," it says. Matthew 11:20-24 has Jesus condemning multiple cities to destruction because they didn't seem to like what he was preaching. Luke 10:10-15 makes essentially the same point.
What happens to them, certainly anybody who has no repented by the time of His arrival will not see the thousand years. Nor is everybody expected to repent by then, if it was to be that way then the prophecy about the 2/3 of living Gentiles would not be given to His sword. This isn't hatred towards the un-repented, it is done to show the remaining 1/3 just what Godly power actually looks like from a 1st person POV. If this was hatred then Judgment Day would not have these coming back to life (to stand before God himself). They just aren't gathered at the beginning of the gathering, they are gathered just before the end of the gathering.
There is even instruction to cast out members of the Church if they refuse to follow the rules, it may not be a good thing for their bodies but their should still belong to God, and that part of them He will keep safe from harm.
1Co:5:5:
To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
1Co:5:6:
Your glorying is not good.
Know ye not that a little leaven leaveneth the whole lump?
1Co:5:7:
Purge out therefore the old leaven,
that ye may be a new lump,
as ye are unleavened.
For even Christ our passover is sacrificed for us:
1Co:5:8:
Therefore let us keep the feast,
not with old leaven,
neither with the leaven of malice and wickedness;
but with the unleavened bread of sincerity and truth.
