"i'm fine with gay people, but they just need to realize that it's a sin"
"There are but two things in this world, science, and opinion." ~Hypocrates
BELIEVING that homosexuality is a sin, is an OPINION. And people are free to have that opinion, it's just not scientifically correct. What I stated is a scientific fact, and if you want thr sources, PM me, because I'm not gonna go around digging for links only to start up a heated discussion in which people disregard fact and refuse to listen because it makes them emotionally upset.
Anyway, this is not to have a religious debate either, since "science vs. religion" is always a discussion that leads nowhere, regardless of anything.
But I will add one thing, since I know it's bound to be brought up:
No, I don't believe homosexuality is a mental illness, and this is simply because there is no evidence to support the fact, unlike the other two I mentioned. Orientation can really only go in three directions if we speak in strict scientific terms.
And for the sake of putting out there, if you want my opinion (opinion because I'm merely making observations about the world), I personally believe bisexuality to be the natural norm, with society conditioning people into heterosexuality to preserve traditional value systems, and homosexuality coming out as a counter to the extreme repression of the other side of the spectrum with people who might lean more in that direction.
Reason I say this because if you look at nature, you notice that animals have no problem having physical and sexual intimacy, regardless of gender. Dogs, Cats, Apes, Dolphins, etc... will all **** without much care for the notion of "orientation."
If you look at humans, the same can also be seen in societies in which conservative values were not overly dominant. Take ancient Greece, or feudal Japan for example, in which homosexuality was perfectly fine and even common even among pairings that had families, because society didn't deem it as amoral.
The point I'm trying to make is that humans, and basically all creatures that reproduce SEXUALLY, have a biological NEED for sexual intimacy, regardless of anything. Society just conditions us in one way or another. Humans are creatures who are meant to love universally, biologically speaking. We are social creatures after all.
For example, if you put a man and a woman alone on an island, they will undoubtedly, eventually ****. Doesn't matter how much they might hate each other before hand, nature will run its course, it's in our biological programming (see Maslow's Hierarchy of Needs).
Now, take two straight men, do the same thing, and they too will eventually ****. Prison is a perfect live example of this, straight men develop feelings for other men out of sheer NEED. It'd be the same if you put two straight women alone on an island.
So, what if you put a gay man, and a gay woman entirely alone on an island with no one to talk to a la Blue Lagoon? Well, I'd say the same thing as our other cases, I don't see why it would be any differently. You are removing all social pressure and conditioning, and allowing these two humans to define what is right and wrong, similar to Lord of the Flies.
Anyway, my two cents, bear in mind that I say this as a heterosexual male, with no interest in really eloping with a man. I'm not undermining the effects our environments have in shaping WHO we are, I'm merely looking at the biological. But, had I been born in a different society, and raised with values which made it normal to be bisexual and polygamous, would I be those things? Well, looking at nature, I'd say it's very possible. Nonetheless, we always have choice, and I can choose what I feel comfortable with based on how I was raised. However, regardless of how I might personally feel about something, that doesn't stop me from observing the world around me, and accepting ideas that might involve paradigm shifts in my perspective. I think that if you look strictly at nature, it's easy to see what the correct answers might be in all cases. That's my point. And yes, THIS would be an unpopular opinion.
