Well I told myself I wasn't going to get into this but I cant resist a good philosophical debate. Although this is the internet so things rarely (if ever) turn into debates and are just one sided arguments, however I shall add my two cents in for previously stated reasons I find it difficult to stay away from touchy subjects because I find they broaden the mind for those willing to look into them from an 'open perspective' (more meaning to someone willing and able to look at things from multiple points of view)
The following is to be taken with a grain of salt as they are of one persons line of thought on the subject and derived from personal observations and experiences and in no way reflect that of the broader majority but tries to bring a different light onto the subjective from a specific point of view
In the sense of Bi-sexuality, It would have to be stated that it just seems like a fallacy. As people tend to lean one way or the other, I would personally delve much deeper than the surface of this as to state that It's not so much as what your attracted to as it is a sense of selfishness. As from personal experience with the people around me whom attribute themselves to being 'Gay' I have yet to meet one that does not fail to fall under the pretext of it satisfying their selfish desires. However the same could easily be attributed to Heterosexuals as well, none can escape the confines of selfishness however one typing does insure the continuation of the Human genome and one does not. One could with that knowledge say that someone whom classifies as a homosexual would indeed be more selfish so as to not inherit the repercussions of parenting a child. However this is a tenuous stance and one that can not be easily defended but on a subconscious level is most likely shared by a majority of the United States society. And from here on out whenever I use the term "This Society" it is in reference to the USA as that is the society in which I was raised and live in which is therefore all I can be accredited to knowing.
Homosexuality is at the heart a very selfish nature but again humans are selfish beings. If you classify as homosexual think, when was the last time you did anything for your partner without at some even minuscule amount of time think how it could benefit yourself. (now be advised as I feel I need to keep warning this is a tenuous route that I am taking here but I am going to try to the best of my ability to show it from every angle possible and this is only one of several different outlooks and in should no way be attributed to my own personal beliefs but from my observations of this societies ingrained core belief values which deny or not are in some way truly part of the foundation of this society)
Homosexuality tends to revolve around ones self and focuses its energies on fulfilling ones selfish desires. At its nature it is incapable of thinking about the other person as if you go with just pure sexual pleasure only one person is able to obtain complete satisfaction at a time it is incapable of being mutually beneficial. Among the desire of selfish satisfaction is the disregard of the other person while obtaining such satisfaction, IE the use of toys or in the case of the Men the entering of orifices in which were not meant to be entered (AKA Anal)In the first example of toys you have the possible use of a strap-on which can be used to gran the other sexual pleasure and fulfillment. However their problem that arises with that is that a strap-on is an inanimate object and has no nervous sensors, so by that statement the tool is incapable of feeling pain. however the person on whom it is being used can and in some cases does indeed feel pain. in the second example is the Male on Male contact in which one sodomizes the other. and make no mistake the legal definition of those acts is sodomy, ironically in that regard sodomy is a crime (go figure). Numerous cases arise of Hernias developing in Men and women who practice anal sex, rare is the individual whom will not after some time develop such a hernia. Both of these examples attribute to the selfish desire of fulfilling personal pleasures.
Well there is more I could go on with the previous topic but I believe that for this particular part of the debate of mine is enough of that for now.
One other thing that was brought up is someone saying that fair few people can truly claim to be 100% heterosexual. I would have to say that that would be false, that the majority of those that fall into this category are truly that. and the ones that show overt discrimination are people whom are not comfortable enough in their own skin, and have yet to truly figure out who they are. There are many people whom are heterosexual and can with complete confidence look at someone of the same gender and find them attractive and verbally state such. this does not take away from their claims as to being completely heterosexual it mearly states that they are comfortable with who they are. I myself can objectively look at other men and find them attractive, there is nothing wrong with this. In fact it is healthy as it should be and is the means of us to figure out who is our competition, the human drive to find a suitable mate. Women have been doing this for years and it is not looked down upon however with this society among the men it typically is and is misunderstood. While i can find other men attractive and visually pleasing it does not mean that i am at all attracted to them sexually, in fact for myself i find the thought of engaging in Homosexual relation to be a turn off for me and have no desire to partake of such situations.
With this I leave you, it has been enjoyable to put out these hypothesis. (TL/DR? then you missed the entire point and many key points)(WTL/DR? You saw something which you wholeheartedly objected to and are now going to start a flame war. Continue...)
