Just so we are all clear. mac is using a definition of "natural" from Natural Moral Law which in turn is derived from Aristotelian Philosophy. Most people stopped using his definition of "natural" in the Medieval ages. The Catholic Church and other orthodox Christian sects have kept it alive. His definition of "natural" is a teleological construct. He believes that everything is designed to serve a purpose and if it does not serve that purpose then it is an "unnatural" act. This form of Aristotelian Philosophy was abandoned by most of the world hundreds of years ago since it was based entirely upon speculation and conjecture.
For example, anal sex is "unnatural" because it does not lead to procreation. The rectum is not a reproductive organ. By extension, masturbation and oral sex are equally as "unnatural" since they don't lead to procreation. The hand and the mouth are not reproductive organs. In vitro fertilisation, which is the process of fertilising an egg with a sperm outside the body is also considered a highly "unnatural" act.
Most people today use an empirical definition of "natural". Empiricism is the basis of science, and it holds that observation and measurement are the key to understanding the world. As such, the modern definition of "natural" is that which is observable and measurable. Homosexuality is "natural" by this definition because it can be observed occurring prevalently in the higher animal kingdom.
So nobody is speaking the same language as mac. He is using an ancient and outdated worldview.
