I don't know why you keep bringing Rom 1 into the discussion.
To show you that the death penalty was not exclusive to the Old Testament.
The MADs shun anything to do with the Law,
False.
Do we then make void the law through faith? Certainly not! On the contrary, we establish the law. - Romans 3:31

but you make me think the OT Laws' punishments are still to be enforced.
You need to stop thinking in terms of "OT laws" versus whatever else you're comparing them to.
It's impeding your thinking.
You need to think in terms of "God's laws." I repeat: God's standards of justice are absolute. If a man kills another innocent man, the just punishment for his crime is to be put to death. Life for life. It doesn't matter whether he's in ancient Israel or in modern day New York. As I just mentioned to Skeeter, what I want is for our nations laws to reflect God's laws, as Israel's Mosaic Law did. I am a theonomist.
The death penalty is not exclusive to the Old Testament. Even Paul, who was no longer under the law, said that if he had done anything worthy of death, that he should be put to death.
For if I am an offender, or have committed anything deserving of death, I do not object to dying; but if there is nothing in these things of which these men accuse me, no one can deliver me to them. I appeal to Caesar.” - Acts 25:11

Paul upheld the death penalty!
OK, I see your perspective now...an insertion of your own POV regarding what Paul would have us do.
But Paul isn't calling for any death penalty.
For if I am an offender, or have committed anything deserving of death, I do not object to dying; but if there is nothing in these things of which these men accuse me, no one can deliver me to them. I appeal to Caesar.” - Acts 25:11

Just that the sinner/criminal is worthy of death.
And the one to enforce that, here on earth, as far as crimes are considered, is the government:
Let every soul be subject to the governing authorities. For there is no authority except from God, and the authorities that exist are appointed by God.Therefore whoever resists the authority resists the ordinance of God, and those who resist will bring judgment on themselves.For rulers are not a terror to good works, but to evil. Do you want to be unafraid of the authority? Do what is good, and you will have praise from the same.For he is God’s minister to you for good. But if you do evil, be afraid; for he does not bear the sword in vain; for he is God’s minister, an avenger to execute wrath on him who practices evil.Therefore you must be subject, not only because of wrath but also for conscience’ sake. - Romans 13:1-5

A sword is not something you use to beat someone with. A sword is used to kill people. Again, Paul is upholding the death penalty.
Christians are to love and forgive,
LITERALLY EVERY SINGLE TIME I have this conversation with someone, they always make this or a similar statement, that Christians aren't supposed to do these things, or we're to love and forgive, or "we're no longer under the law," all of which are irrelevant to what I'm talking about! I'm not talking about Christians! I am talking about how governments should enforce laws upon the general population!
And NO! We are NOT supposed to just "love and forgive"! You're sounding like PureX!
We are to love, yes, but we are to also HATE EVIL! That doesn't mean "hate the sin and love the sinner," it means hate the person who sins, while loving them enough to warn them that their sin will send them to hell when they die, but that Christ can save them! How do we do that? THROUGH THE LAW! The law is the very tutor we need to use to bring people to Christ, and that comes STRAIGHT FROM THE BIBLE!
We are to forgive, BUT ONLY IF (and that's a HUGE "if") the person repents! If they don't repent of their wrongdoing, and you forgive them, it teaches them that repentance is superfluous, unecessary, and that they don't need to repent before God because He'll just forgive them whenever they do anything wrong! When you forgive someone a) without rebuking them and b) without them repenting, you are quite literally forgiving them straight to hell!
but if the civil law enforcers want to kill, that death is on their heads.
Once again, IT IS THE GOVERNMENT'S RESPONSIBILITY to punish criminals! It's NOT OPTIONAL.
Those of us who have been baptized into Christ won't usurp a power only God is entitled to.
If the government was to appoint you to be the head judge over the entire nation, would you be able to condemn the wicked?
