You give examples of animals displaying homosexual behavior. Not homosexuality. Can you please give me examples of homosexuality in animals. As in homosexual acts, not behaviors.Try checking the dictionary before you make a verbal gaffe such as this. Behavior is, by definition, the way in which something acts or conducts itself.
In short, if animals display homosexual behavior, they do so by performing homosexual acts.
You are wrong. Let's say I have no interest in the opposite sex. This could be considered "exhibiting homosexual behavior." Although, I have no interest in members of my own sex either.
A "homosexual act" is clearly something different. Now, once again, since many on this board claim that the act of homosexuality is found abundantly throughout the world, where is the proof?
