I was reading Gary Whitta's Google+ stream and came across a video with the title Herman Cain: ‘Show Me The Science’ That Being Gay Is Not A Choice I don't know who Herman Cain is, nor do I really care, but the question itself seems weird to me. It's obviously not a choice! Let me explain...
Assume being gay is indeed a choice someone makes. That, by extension, means being straight is also a choice since every man or woman could, theoretically, swing either way and it's all up to them. This means that everyone reading this, straight or gay, could suddenly decide to "try the other side" since it's all just a matter of making the decision. Is that really the case? I can tell you right now, it's not. I'm straight and it would not be possible for me to make a choice to suddenly turn gay. I mean, sure, I could maybe pretend, for whatever reason, but to actually have a physical relationship with a man? No. Not possible. By logical extension then, if someone is gay it's as little a choice for them as being straight is a choice for me.
Of course, there are people in between, bi-sexuals if you will. They are the only ones who I guess could make a choice either way. The only logical conclusion is that people like this Herman Cain, who belive being gay is a choice... they must then have faced that same choice, right? Aything else makes no sense at all. They must be somewhere in the middle of the straight - gay spectrum; they chose to be straight and therefore believe all people who are gay simply chose the other side.
