Why does everyone...

Most of them believe it's wrong due to their religion of on basic terms,their own beliefs. But! Let us take Christianity for example. Not every Christian believes that it is a sin. Same goes for every other religion. It's all a matter of belief.

Everyone?

Well it's their religion, they have the right to believe in whatever they think is right, just like u have the right to believe heterosexual is okay and that is amazing
Personally I don't care if someone is heterosexual it doesn't affect me in any way possible.
But to answer your vraag idk

It's quite new for pop culture to accept any other sexuality, so people are simply frightened. Take any religion, race, idea that was introduced to society...people shun it and go against it because people are simply afraid of change and how this change is going to effect them and their prosterity.

At least, that's my view on it.

Ignorance I suppose.

I'm Christian,but I'm fine with every sexuality. But i think it's because people might think it's disgusting of weird.

The majority of Americans and Europeans at least don't ya know.

I support homosexuality. Almost everyone in the Fanpop supports it. I dislike homophobea. Homosexuality is natural. :]

idk but i support gay rights

It is, I don't think it's right.
Shoot me bitch.
*shrugs*

I think it's funny how just 2 of 3 years geleden
everyone knew. Wait, 'most people' I'll just say that
knew let's say gay marriage was wrong.
u couldn't even bring up that subject to the prez.
Now just because it's 2013 it's meer like a normal thing. Now that it's on TV and your favoriete stars accept gay marriage lets say that.
Your opinions change so easily.

Now I'm not saying I hate
gay people, I'm not gonna say to a gay couple u suck ass, buuuttt It's not really my problem.
I like yaoi I think to guys being a couple is like hella sexy.
To tell u guys the true I have really no opinion about it. *smiles* Sorry if I sounded a bit rude?
I meant no harm. lol

Well to most it is because of their religion.
of because they think it's unnatural.
Even though it's been proven to be natural.
...And even if it was unnatural I don't see how that's a bad thing...

But not to fear. With every dag that passes homophobia is dying meer and more. And 40 years from now homophobes will feel just as ridiculous as the people decades geleden who were against interracial partnership.

Not everybody does. Most people believe its a sin against The Bible (It really isnt tho) So thats why. But I dont see the problem. (I'm Asexual so.)
