First of all, there will be opinions expressed here that may cause controversy. Sorry 'bout that chief, but that's the way it is.
To begin with, let's correct some of the rhetoric surrounding the “gay” issue. I'm tired of having to point out to people, being gay is NOT “normal”; it is “natural” without being “normal”. According to Merriam-Webster, “Definition of NORMAL 2a : according with, constituting, or not deviating from a norm, rule, or principle”; whereas “natural” “Definition of NATURAL 2a : being in accordance with or determined by nature b: having or constituting a classification based on features existing in nature.” In short, in other words, though being gay is NOT the “norm”, it is fully natural, i.e., there is nothing condemnable about being or not being “gay”.
Let's stipulate that peoples' sexual orientation is none of my business; the only time it becomes my business is when it comes to my being propositioned. I tend to agree with Heinlein on this one; it is always nice to be asked, I don't have to agree to it but it is nonetheless nice to be asked. However, someone's sexual practices have absolutely nothing to do with me. Unless I ask someone about the topic, it is not something that generally comes up in conversation. I don't bang on about my personal sexual orientation and don't really care to explore others' orientation.
As to the question of “choosing” to be gay or heterosexual, one needs to ask of those “heterosexuals” when did they “choose” to be heterosexual? All of us, every man jack out here, have both homosexual and heterosexual aspects. It's very similar to the old Carlin routine where, as George said, “You're in the dark, rubbing up against someone, kissing and fondling, having a good time and, when someone turns on the light and you find out the person you were fondling turns out to be the same sex, we're all trained to shriek “ABNORMAL” and run into the night screaming. But, it felt good.” In other words, what Carlin was saying is that the actions themselves were pleasing but our cultural training says it is something evil. Nonsense!
Do people “choose” to be gay? I don't know, do people “choose” to be heterosexual? If quizzed, I wouldn't be able to tell anyone when I “became” heterosexual, I just noticed early on that I liked girls, even before anything of a sexual nature had developed. Do people “choose” to become a despised minority? I doubt it. I'm certain some people “choose” to express their “gay” side (bad experiences with the opposite sex are quite possible to cause one to “choose” not to repeat those).
What I have long contended, unless one is having sex in public, either heterosexual or homosexual, one's orientation is absolutely immaterial. After all, there are laws on the books regarding PDA (public displays of affection) and, though I believe such laws may go a bit far, I feel they should be applicable no matter what kind of “affection” is being displayed.
In conclusion, whether one “chooses” their orientation or they come by it “naturally”, that should hardly be any kind of a criteria of evaluating a person. Of course, it goes without saying that I have friends, close friends, who are gay. So? I did NOT choose them because they were gay, I chose them because of who they are as people. Period.
