Homosexuality is not a rare by any means. There are consistent rates of homosexuality and these differ between demographics, but in North America that rate is around 10-13% (source). So gays are about as rare as people who are left-handed (10% of the general population) but for some reason the former is far more threatening than the later.
When I notice someone is left handed, I don’t judge him and tell him he is wrong and perverted; I find it rather interesting, like a fun-fact about that person. Studies have even found benefits to left-handedness; John Hopkins University found that of college educated people, left-handers earn 10-15% more than their right-handed counterparts, and the brains of left-handed people are structured differently allowing better use of both sides and a wider range of abilities (Chris Mangus, University College London).
So it would be silly to label left-handed people as demented, sinister and wrong for civilized society… yet that is exactly what the church did less then a century ago. In fact, nuns in catholic school had a different name for the left-hand: “sinistra,” the use of which would result in an abusive wack from the ruler. Years later, neuroscientist would discover that the right-side of the brain controls the left side of the body, making the churches belief, that one side is “right” and the other side “wrong,” completely moot. That same ignorance is alive and well in right-wing politics.
Indeed, it would be easier for scissor manufacturers if all people had the same preference for right-handedness, but maybe there are confounded benefits to having a small percent of the population (say 10%) who pursue the contrary, for example left-handeness and homosexuality. Maybe some people are meant to be different for a reason. I think Charles Darwin would agree that a healthy ecosystem depends heavily on its biodiversity. Perhaps, maybe the same can be said about certain in-born behaviors in human beings, or any species for that matter. The success of so many different life forms seems to suggest that diversity, and having variations in behaviors and tendencies, is intrinsically beneficial for the system as a whole.
Close-minded people, however, do not see the potential in diversity, and therefore have no tolerance for what is outside the norm. They feel afraid and fearful of what they do not know or understand. They see all Muslims as terrorists, all Germans as Nazis, and all gays as pedophiles. Have terrorists been Muslim, Nazis German, or pedophiles gay? Yes, but to link all of those people with the worst then you are doing a serious injustice to all those innocent people that are for the most part, good people.
Aight, I’m going off on a tangent, so I’ll rap it up…
Gays are a necessary piece of the pie, even if we don’t know why.
Some of us are meant to be gay, ‘cause baby we were born this way!
Long Live Lady Gaga!
