Homosexuality is natural

Alright so I guess ill be traditional with a case;Just to start with some Definitions:Natural: existing in nature and not made or caused by people : coming from naturehttp://www.merriam-webster.com...Sex: either of the two main categories (male and female) into which humans and many other living things are divided on the basis of their reproductive functions.http://www.merriam-webster.com...Gender: the behavioral, cultural, or psychological traits typically associated with one sex http://www.merriam-webster.com...Gender identity: refers to “one’s sense of oneself as male, female, or transgender” (American Psychological Association, 2006). When one’s gender identity and biological sex are not congruent, the individual may identify as transsexual or as another transgender category (cf. Gainor, 2000).http://www.apa.org...Gender expression: refers to the “…way in which a person acts to communicate gender within a given culture; for example, in terms of clothing, communication patterns and interests. A person’s gender expression may or may not be consistent with socially prescribed gender roles, and may or may not reflect his or her gender identity” (American Psychological Association, 2008, p. 28).Ok to start:As the negation I place the BOP STRICTLY on the AFF, I will not accept a BOP and my sole purpose is to negate the resolution while my opponent must prove homosexuality is natural.Contention 1: Homosexuality is a Gender and not a Sex. Homosexual is not a sex, which is derived from nature; but instead it comes from what you identify as, or gender Identity/ Sexual Identity , which is derived from society, The APA states "Sexual orientation is an enduring emotional, romantic, or sexual attraction that one feels toward men, toward women, or toward both. Although sexual orientation ranges along a continuum, it is generally discussed in terms of... homosexual—attraction to the same sex" So being homosexual is related to one identity that they assign to them selves, some may say it is naturally because animals participate in homosexual acts however the methodology of these studies relates kinship to homosexual activity. Kinship however is not a homosexual act. Thus Homosexual activity is not natural.NAARTH states "Anyone engaged in the most elementary animal observation is forced to conclude that animal "homosexuality," "filicide" and "cannibalism" are exceptions to normal animal behavior. Consequently, they cannot be called animal instincts. These observable exceptions to normal animal behavior result from factors beyond their instincts. To explain this abnormal behavior, the first observation must be the fact that animal instincts are not bound by the absolute determinism of the physical laws governing the mineral world. In varying degrees, all living beings can adapt to circumstances. They respond to internal or external stimuli. Second, animal cognition is purely sensorial, limited to sound, odor, touch, taste and image. Thus, animals lack the precision and clarity of human intellectual perception. Therefore, animals frequently confuse one sensation with another or one object with another. Third, an animal's instincts direct it towards its end and are in accordance with its nature. However, the spontaneous thrust of the instinctive impulse can suffer modifications as it runs its course. Other sensorial images, perceptions or memories can act as new stimuli affecting the animal's behavior. Moreover, the conflict between two or more instincts can sometimes modify the original impulse. In man, when two instinctive reactions clash, the intellect determines the best course to follow, and the will then holds one instinct in check while encouraging the other. With animals that lack intellect and will, when two instinctive impulses clash, the one most favored by circumstances prevails.[4] At times, these internal or external stimuli affecting an animal's instinctive impulses result in cases of animal "filicide," "cannibalism" and "homosexuality." http://www.narth.org...Contention 2: Gender is not derived from nature. Gender is an intellectual ideal formed by society not something found in nature. "The most important factor was the adoption of gender in the 1970s by feminist scholars as a way of distinguishing “socially constructed” aspects of male–female differences (gender) from “biologically determined” aspects (sex). This distinction is now only fitfully respected, and gender is often used as a simple synonym of sex. The rise of gender has been accompanied by complaints that the word should refer only to grammatical categories (Fletcher, 1991; Goodhart, 1992; Smyth, 1968) or to socially but not biologically determined differences (Fishman,Wick, & Koenig, 1999; Kim & Nafziger, 2000; Lewine, 1994; Pearson, 1996; Walker & Cook, 1998; Wilson, 2000)." So gender is not a biologically or naturally determined thing, instead it is determined by gender, or your sexual identity which is SOCIALLY CONSTRUCTED.
