Those are disgusting words which contradict God's word: "Do I desire the death of the wicked? says the Lord God. Is it not rather in his repenting of his ways that he may live?" (Ezekiel 18:23)
There's a story in the Gemara of 2 rebellious Jews who would constantly greatly bother Rebbi Meir and they would hurt the faith of other Jews, and Rebbi Meir started to pray that Hashem should take away their lives, that there's no point for creations like that to continue existing, but his righteous wife Bruria overheard his prayer praying for the wicked to pass away and rebuked her husband and told him "stop praying for them to pass away! Rather pray that they change their ways and return to Torah!" And he did, and they ended up fully repenting and devoting their lives to become great in Torah knowledge.
I don't wish death upon anyone, including Arabs. They should stay in their own lands and live very long and very happy lives.
The first verse you quoted out of context talks about Jews who already repented for their sins, not Amalek who are very proud of being Amalek.
The story you brought is talking about Jews who caused terrible noise that bothered Rabbi Meir and made him unable to focus on his Torah study. Not Amalekites who threw Jewish kids to wells and shot their parents in the head in the "Holocaust of Bullets", and glorify this monstrous mass murder to this very day.
You are calling yourself a Noahide, but you are preaching for Christian "morals" (that brought endless misery to the entire world). In Judaism there is no giving the other cheek or loving the enemies.
When Amalekites die Jews are happy, we celebrated the death of one famous Amalekite (Haman) and his henchmen as recently as this Purim.
"when the wicked perish, there is song" (Proverbs 11:10)
"Your enemies will lie to you, but you will tread upon their heights" (Deuteronomy 33:29)
