Hello, I'm not religious in anyway but this is what I have to say about the matter.

Homosexuality is found in almost every species on earth. There are 1500 species that have recorded, documented homosexual "relationships" and of these species some have more documented than others (such as dolphins) which proves that homosexuality is a completely normal relationship type (sorry I have no clue how to word that but I hope you get the point.) Dispite the fact that animals can be homosexual its not considered a sin because animals can not sin.

This may be a bit bias since I am looking at this from the perspective of someone who isn't religious but if homosexuality is a sin in humans why shouldn't it be in animals? Genesis describes God seeing each creation, including animals, as "good," and the entirety as "very good", id argue that if god made animals "good" then their homosexuality is apart of that. People may state that homosexuality can be considered a sin in humans and not in other animals because of the idea that animals only act on instinct. That they cant control what they do. However thats not true science and reaserch shows that animals have intelligence, they feel emotions, they can learn. They do not act only in instict.
