Now, take a look at this: "scientific research has revealed that more than 450 different kinds of animals engage in homosexual activity" (Source)
Animals are as natural as it comes. Male animals bang male animals and female animals scissor with female animals. Animals, which are natural, take part in homosexuality. Homosexuality is natural, by a textbook definition. So, that "unnatural" claim is utter bullshit. Just as a head's up for future reference, so you'll look less like an undereducated schmuck.
