The existence of SAD confirmed:
To our knowledge, while there is yet no scientific studies confirming or denying the existence and nature of SAD, or that SAD is an exacting description of certain sexual attractions, we believe that this conclusion is easily derived through common sense and reasoning.
However, rather than offering up a logical syllogism in support of our assertion, we believe it may be more beneficial to ask a series of questions which are designed to engender mutual agreement, as well as guide the reader into making our case for us. Given the of-times rancorous, prejudicial, divisive, and emotionally charge discussions associated with this issue, and the vulnerability for misunderstandings, false accusations, etc. (such as those we have already experienced--please see the section on "Discussions" below), we believe this to be the best strategy for fostering productive civic dialogue.
As an assistive device, we will, at times, make use of a "key and lock" metaphor.
The argument for the premise of design and function:
1. Physically speaking, do you agree that the adult (sexually mature and reproductively capable) sexes (male and female) have their distinctive and respective sexual design and function (even as a key is distinctive in design and function from the design and function of a lock)?
2. If not, why not?
3. If so, do you agree that while the adult sexes have their distinctive and respective sexual design and function, they are, never-the-less, designed to sexually fit and function together (even as a key and lock are designed to fit and function together)?
4. If not, why not?
5. What do you view as the sexual design and function, in nature, as predominately manifest across the entire spectrum of the animal kingdom (including humans), for the two adult sexes (male and female)?
6. Do you agree that adult males and females are designed to sexually fit together and function as the sole means, in nature (at least for those animals, including humans, where there are males and females), for uniting the two critical components of reproductive life (sperm and egg)?
7. If not, why not?
8. If so, do you see this sexual design and function as being one that is rationally assumed (a priori), and obvious (prima facia)?
The argument for the premise of purpose:
1. What do you view as the purpose(s), in nature, as predominately manifest across the spectrum of the animal kingdom (including humans), for sexual attraction (sometimes referred to scientifically as libido, estrus, etc.)?
2. Do you agree that the sole purpose, in nature, for sexual attraction, is to motivate the two adult sexes to sexually function as they are designed, and have sexual intercourse, so as to propagate the respective species (not unlike the key locking and/or unlocking the lock)?
3. If not, why not?
4. If so, do you see this purpose as being one that is rationally assumed (a priori), and obvious (prima facia)?
The argument for the premise of order in nature (natural order).
1. Do you agree that there is an order to nature--i.e. things in nature are intended to work in a certain way (even as a lock and key are intended to work in a certain way)?
2. If not, why not?
3. If so, do you agree that the order of nature is manifest in, and a product of, the natural thing's design, function, and purpose (even as the order of a lock and key is manifest in, and a product of, their respective, and shared, design, function, and purpose)?
4. If not, why not?
5. If so, do you see this order in nature as being one that is rationally assumed (a priori), and obvious (prima facia)?
The argument for the conclusion that sexual attraction and sex between the two adult sexes is the order of nature (natural order).
1. Given that the the order of nature is manifest in, and a product of, the natural thing's design, function, and purpose; and given that the sexual design and function of the two adult sexes (male and female), and the sole purpose for the sexual attraction between the two adult sexes, is to propagate the respective species; do you agree that sexual attraction and sex between the two adult sexes is the established order of nature (even as the key locking and unlocking the lock is the order of keys and locks)?
2. If not, why not?
The argument for the premise of disorder in nature (natural disorder).
1. Do you agree that where there is an order to nature--i.e. where things in nature are intended to work in a certain way according to their design, function, and purpose, that there is also the possibility of disorder in nature--i.e. where things in nature do not work in a certain way according to their design, function, and purpose (not unlike a key and lock not working according to their design, function, and purpose)?
2. If not, why not?
3. If so, do you see this disorder as being one that is rationally assumed (a priori), and obvious (prima facia)?
So you have a situation where Wade uses a terrible argument to draw the conclusion that homosexuality is disordered. It's no surprise that people would see this as bigoted, just like many see the same in sketchy biological arguments that are supposed to establish the general intellectual superiority of whites to blacks. The conclusion implies something very negative about a group that reinforces a history of illicit prejudice and discrimination and the argument to get to that conclusion is shady.
Now, on an aside, Wade is likely to charge me with not addressing his argument. To that, I have two replies. First, I did address it at length, with him, on ZLMB. I find that satisfactory. Second, my post is simply addressed to those who would read that argument and already agree with me about its problematic nature.
