Calling homosexuality unnatural is the most ridiculous thing I’ve ever heard. Everything we do is “unnatural.” Cars. Books. Computers. Jobs. Glasses. Medicine. Government. Clothing ourselves. Farming. Marriage itself is unnatural! Men and women having different genitalia doesn’t prove that the sexual relations between them are “natural” just because that’s how reproduction occurs. Your penis or vagina doesn’t know what’s stimulating it, and it doesn’t care. You brain does, but your genitals don’t. All your privates know is that they’re being aroused, and their natural biological functions will react accordingly. Someone feeling sexually aroused is natural, and it doesn’t make it somehow unnatural if a person with the same genitalia is doing the arousing. The argument from unnatural is the most bogus attempt ever at justifying the denial of same-sex marriage.
