OP "I think homosexuality is totally wrong and unnatural, what do you think?"
I think you are thinking in a normal heterosexual way.
A persons morality decides whether homosexuality is right or wrong & results will vary from person to person, but homosexuality is not unnatural.
As you are (now)aware homosexuality is perfect natural(also normal) in many parts of the animal kingdom & especially amongst Bonobo Apes.
However does this make this prove homosexuality right? No,it is still an individual judgement dependant on morality/ethics.
To focus on Bonobo Apes;
Parties of Bonobo males also "'patrol' for the unfortunate neighbouring males that might be travelling alone, and attack those single males, often killing them.". Bonobo apes are not perfect.
To draw a long bow;
Some animals & humans(usually children) also eat faeces (excrement expelled through the anus or cloaca during defecation).
Who am I to judge or impose my morals on them?
Let them eat until their bellies are full, but not at my dinner table please.
