Glad you found it of interest Sally.
Change, yes Falun Dafa believes that homosexuality is sinful behaviour, there is no denying this. But then many spiritual practices also believe this is so.
This is what Mr Li Hongzhi has said about the matter of Interracial children in some lecture excerpts:
1)
"The issue of the interracial children I have just mentioned has told mankind a heavenly secret, but it is not that we would do anything. I said that I have done something even greater in the sense that I can also save a person of mixed blood, but I can only save him in this period of time. Though oriental people and Westerners all live on earth, man does not know that there is something separating the East and the West.
It is well known that oriental people believe in the so-called "nine". They like the sound of it, which implies everlasting. "Eight" is pronounced as "fa", implying making a fortune. These kinds of things can indeed have a little bit of effect in the East, such as geomantic omen telling or landscape analysis, etc. But when applied in the West, they appear to be ineffective and do not work. They do not work with the white people. Then again, the so-called astrology or some phenomena believed by the white people do not work with the oriental people either. Some people think that they work.
That is because you think they work. In fact, they don’t. Why is it then? It is because the white people's biosphere has its special physical matter formed in its own dimension while the oriental people's biosphere has the special matter made up with their life. Such things run through the makeup of one's life. Thus, the two sides are not the same.
After races are mixed up, you will find one’s child born to be an infant of mixed blood. However, there is a partition in the middle of this child's life. If it is separated, he will be physically and intellectually incomplete or a person with an incomplete body. Modern science also knows that it is getting worse one generation after another. It would be like this. Of course, if such a person wants to practice cultivation, I can help, and I can take care of it. It cannot be done to a non-practitioner."

"...Why is there no Buddhism in the world of the white people, and no Christianity in the world of the oriental people? Strictly speaking, there is not. I remember that Jehovah and Jesus all said in the Bible or books as such, "You should not go to the East." There are other things said, but I only remembered this sentence, "You should not go to the East," telling his disciples not to pass on the teaching in the East. His disciples did not listen to his words and followed the expeditionary forces to the East. A problem then occurred.
The races in the world are not allowed to be mixed up. Now, the races are mixed up and it has brought about an extraordinarily serious problem. Once races are mixed up, one does not have a corresponding relationship with the higher levels, and he has lost the root. Mixed races have lost their roots, as if nobody in the paradise will take care of them. They belong to nowhere, and no places would accept them. Therefore, you find the place where the continents of Europe and Asia meet a desert in the past and a depopulated zone.
When the transportation means were not advanced, it was difficult to pass through it. With the progress of modern means, all these are broken through. Thus, races have become increasingly mixed up, which can lead to serious consequences. Of course, I will not go into details. I'm just saying that the higher levels do not recognize such a human race...."

"...The way alien beings get human beings to shake free of the gods is to mix the races, causing human beings to become rootless people, just like the plant hybrids people make nowadays. South Americans, Central Americans, Mexicans and some people in South East Asia— all of these races have been mixed. None of this can evade the gods’ eyes. Alien beings have made rather extensive preparations for overtaking human beings..."
4 )
“...No one knows that even though many people talk about believing in Buddhas or believing in gods, the truth is, if you aren’t someone from that particular god’s world he won’t save you whatsoever. I once made a statement that whether it’s Christianity or Catholicism, in their paradises there are no Eastern people. This is an absolute truth which man doesn’t understand. Yet Western religions went to the East with the Crusades, and the way they spread wasn’t good to begin with, since both Jesus and Yahweh prohibited their disciples from spreading the teachings eastward..."
As for the alien phenomena, indeed your right. Mr Li Hongzhi talked about this topic in a Time Asia interview he gave a number of years ago:
