Cherry-picking the OT is common among racists, bigots and other haters who use claims of being Christian as a shield. Note that those who do so rarely, if ever, conduct themselves as Christians.
If they did, they'd be quoting these NT quotes of Jesus instead of cherry-picking from the OT to spread hate:
Matt 22:37-40 Jesus said to him, “‘You shall love the LORD your God with all your heart, with all your soul, and with all your mind.’ “This is the first and great commandment. “And the second is like it: ‘You shall love your neighbor as yourself.’ “On these two commandments hang all the Law and the Prophets.”
John 13:34 “A new commandment I give to you, that you love one another; as I have loved you, that you also love one another.
2John 1:5-6 And now I plead with you, lady, not as though I wrote a new commandment to you, but that which we have had from the beginning: that we love one another. This is love, that we walk according to His commandments. This is the commandment, that as you have heard from the beginning, you should walk in it.
John 14:21 “He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him.”
