Would you be offended if a Greek person called you “ethne” too? It has the same meaning, i.e. “nations”.
Your accusation that Jews who do not believe in Jesus are “lost” is utterly un-Biblical. Nowhere do any of the Apostles say such a thing, nor does Jesus Himself.
Goy do mean nation, but has later evolved to encompass negative connotations as well. I have studied semiotics.
“Long before Roman times it had also acquired the meaning of someone who is not Jewish.[7] It is also used to refer to individuals from non-Jewish religious or ethnic groups. The term goy is not inherently any more or less offensive than the term gentile,[8][9][10] unlike the term shegetz.
As the Jews considered all of the non-Jewish nations in biblical times as polytheistic and idolatrous, the Hebrew word goy had for some time acquired the meaning “heathen”. In a more comprehensive definition, the word goy corresponds to the later term ummot ha-olam (nations of the world).[6]”

So, I would assume it is quite similar to the Christian “heathens” and the muslim “infidel”... in modern parlance..
The first basic tenet of the Christian faith is that Jesus Christ and His sacrificial death on the cross is the only way to be able to receive eternal salvation with God the Father. The Bible makes it very clear that there is no other name and no other way into the kingdom of God other than through the name of Jesus Christ and His sacrificial death on the cross.
If you're a Christian, I'm surprised that you do not know this. The following scriptures are quoting Jesus or an Apostle:
“Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.” The Apostle Peter speaking of Jesus in (Acts 4:12)
“For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all …” The Apostle Paul speaking of Jesus in(1 Timothy 2:5)
Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.” (John 14:6)
“I am the door. If anyone enters by Me, he will be saved, and will go in and find pasture … I have come that they may have life, and that they may have it more abundantly.” Jesus speaking of Himself in (John 10:9)
Jesus said to her, “I am the resurrection and the life, he who believes in Me, though he may die, he shall live. And whoever lives and believes in Me shall never die.” (John 11:25)
Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.” (John 8:12)
And Jesus said to them, “I am the bread of life. He who comes to Me shall never hunger and he who believes in Me shall never thirst.” (John 6:35)
“I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.” Jesus speaking of Himself in (John 6:51)
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.” The Apostle John speaking of Jesus in (John 3:15-16)
Does one have to be Baptized to enter Heaven ?????
