Oh, same-gender relationships, aka homosexual relationships, are quite common in the animal world. In the animal kingdom, there are species which have heterosexuals, bisexuals, and homosexuals.
If the person who wrote the above quote were willing to do some educational research, either online or at a local large public library, he or she would find quite a bit about homosexuality and homosexuals in various species of animals, birds, mammals, and even animals like lizards. In fact, there is one species of a lizard in which there are no males at all. I saw that on a PBS Nature show.
The Whole Bible is NOT God's Word (aka the Word of God). If it were, the word's of the Devil and Humans would not even be in it. Lot's of times, ignorant people read something from the Bible, without even understanding the context and claim, "Since it is in the Bible, God said it!"
In fact, the author called "John" refers to Jesus the Christ as the Word of God. For believers in Jesus the Christ, aka "Christians" since 327 AD, there was no NEW TESTAMENT officially until 397 AD. That was 300 years AFTER the book of Revelation was written. And it was the idea of a supposely converted Emperor, Constantine, that a Bible be created and that a creed be created. It took over 60 years before those so-called "Early Church Fathers" could make up their minds as to what should be in a Bible. Some of the very works that are mentioned in the accepted Books were rejected by those "Fathers" because they did not agree with the Eastern Orthodox's doctrines.
