I can only talk about christianity, my faith and religion. In Jesus Christ there is no difference between nations cause God has send Jesus to justify all men, as revelead to Peter, the apostle:
"Now on the morrow, as they were on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray, about the sixth hour:
and he became hungry, and desired to eat: but while they made ready, he fell into a trance;
and he beholdeth the heaven opened, and a certain vessel descending, as it were a great sheet, let down by four corners upon the earth:
wherein were all manner of fourfooted beasts and creeping things of the earth and birds of the heaven.
And there came a voice to him, Rise, Peter; kill and eat.
But Peter said, Not so, Lord; for I have never eaten anything that is common and unclean.
And a voice [came] unto him again the second time, What God hath cleansed, make not thou common.
And this was done thrice: and straightway the vessel was received up into heaven.
Now while Peter was much perplexed in himself what the vision which he had seen might mean, behold, the men that were sent by Cornelius, having made inquiry for Simon's house, stood before the gate,
and called and asked whether Simon, who was surnamed Peter, were lodging there.
And while Peter thought on the vision, the Spirit said unto him, Behold, three men seek thee.
But arise, and get thee down, and go with them, nothing doubting: for I have sent them.
And Peter went down to the men, and said, Behold, I am he whom ye seek: what is the cause wherefore ye are come?
And they said, Cornelius a centurion, a righteous man and one that feareth God, and well reported of by all the nation of the Jews, was warned [of God] by a holy angel to send for thee into his house, and to hear words from thee.
So he called them in and lodged them. And on the morrow he arose and went forth with them, and certain of the brethren from Joppa accompanied him.
And on the morrow they entered into Caesarea. And Cornelius was waiting for them, having called together his kinsmen and his near friends.
And when it came to pass that Peter entered, Cornelius met him, and fell down at his feet, and worshipped him.
But Peter raised him up, saying, Stand up; I myself also am a man.
And as he talked with him, he went in, and findeth many come together:
and he said unto them, Ye yourselves know how it is an unlawful thing for a man that is a Jew to join himself or come unto one of another nation; and [yet] unto me hath God showed that I should not call any man common or unclean:
wherefore also I came without gainsaying, when I was sent for. I ask therefore with what intent ye sent for me."
Acts 10:9-29
So, for the power of the Holy spirit, God´s covenant with the hebrews now, by the love and sacrifice of Jesus, is extended to all nations, so God do not see diference between nations: "What God hath cleansed, make not thou common."
The same sex union is forbidden cause it is not how God created, since He made man to woman and woman to man. It is the same reason that He does not approve of hibridization of animals, it is not how intended to be, and Jesus Christ did not changed that.
However, for the nations, Jesus did extend the covenant of God to all nations, so there is no longer diference in the eyes of God, all can be saved by faith in the love of Jesus and following his path.
