There's no nicer way to say this but...

It's not anyone's place but they couple's to determine how legitimate their relationship is. Your view of marriage is very cold. I'd like to get married because of my own feelings for another person. I don't care if we'd never jointly own anything because that's not why people get married. People get married so that they can be married. People can also live without chocolate or beer, but they doesn't mean people don't buy them. Yes, love exists outside marriage, but people in love usually want to be married.

But it is. Society determines things.
You romanticize marriage as a matter of love. It's more a matter of logic and a matter of whether you could live with that person for the rest of your life, than of love. We know that love eventually degrades with marriage. Could you fart when in the presence of your girlfriend? I don't even fart when I'm with ukrainian prostitute.
But after you get married...You don't give a damn. Marriage creates families. This is what it is for. Love could, of course be a factor in bringing people a step forward to taking the path of marriage, but love does not keep a marriage going. In fact, it sometimes serves to destroy it.
And why, why on earth would people who love eachother want to get married?
Well, in order to let other people know they are "serious" and not just toying around. To let other people know that they hope to have a future longer than a decade, maximum.
To bring forth children within a proper family.
This is what marriage is for.

Then I especially fear for your children. Teach them a little challenge for authority if only to make sure they don't become victims of it. This should not be taken in context of religion or politics, but any people can become oppressed and they need to have the tools to stick up for themselves.

I really don't know what you're talking about. Nationalism is the very essence of standing up against any authority if the wellbeing of your own people are at stake.
Fear for yourself, not for me, nor for my children.

I don't think of children as a burden, but a joy. And I'm sure they are legitimately children and not some robot (I don't like that turn for children not born of a marriage). Then are you are pro-choice and pro-birth control? (<- I don't mean this offensively or rhetorically, I am just curious)

But unless you are freshly divorced, and receive child money from the father, I'd say you're screwed. Sure, it's joyful, and this is why they dump their newborn babies in front of churches and orphanages.
A child, illegitimate, unwanted and the burden of a single parent, is more of a burden than a joy.
They are "children", but they are born out of a marriage, and are not bound to any of the parties but the one that gave birth to it by any legal or social contract. İllegitimate, they are.
I am not against abortion, however I am not pro-abortion, due to the fact that there are a lot of birth control methods that effectively make abortions only a measure for very extreme cases. But of course, if stupid people continue to have sex without protection, and bring forth their illegitimate pregnancies, they have only two choices. Either get an abortion, to hide their shame, or to bring forth the child.

These are your fellow humans, you're not empathizing with them.

I guess you should get to know me a little bit better before coming up to me with this humanist propaganda.
Of course, they might also be fellow Turks, as far as I am concerned. But they still go against our customs, traditions and culture.
Their marriage is nothing but a mockery of our familial values. No amount of empathy can make me contradict our values, by which I live my life.

Put yourself in their shoes.

When I do that, I come to the same conclusion as I've come to before.

If you weren't allowed to marry the person you loved most in the world and additionally,

There is no such world, comrade Annik.
I could perhaps face opposition from the family of the girl, but then, I'd go back to an age old Turkish tradition. I'd abduct her from her home. That simple.

you were told that your love wasn't legitimate

Well, their love might be legitimate, but they do not fit in the lines of marriage, which is between a man and a woman. Sorry, friend. But this is the way things are. Just because you want it to change doesn't mean it will. Even if it's legalized, people will always think of a man and a woman when thinking of a "married couple".
This is how marriage was put into place.

Marriage has been around longer than most societies and I'd considered no one's business who anyone wanted to marry because that's their choice. It doesn't hurt them and it doesn't hurt anyone else.

Marriage has been around longer than most societies, and in each and every society, it has been exclusively between a man and a woman. Not two men or two women.

If you want a legal union for homosexual couples, you have to look for something else. But no, you want them to be considered "normal" just like a normal couple of a man and a woman, husband and wife.
Even the words for the parties of a marriage "husband" and "wife" are specifically for a male and female, respectively. When people think of a married couple, almost everyone thinks of a husband and wife. This is the way things are. And I think they certainly would not be that way if it shouldn't have been that way.

They should be accepted. There's no reason for them not to be, logically.

Gays? Or their marriage? Well, I accept the existence of gays. I accept their right to exist, just like anyone else. I accept their civil liberties. But marriage is another thing entirely.

Homosexuality is not Down's Syndrome.

Sure, it isn't. But it's close. It's a genetic defect that, in todays world, keeps these individuals from joining normal society as it progressed throughout history. From my viewpoint, such gene defects should be closely examined, and purged from the human gene pool if possible.
Just like down's syndrome.

Left-handedness isn't normal, either.

Is it?

We don't kill people because of it (anymore).

True.

Homosexuality is not a diseases or disorder, it's a state of being.

Just like autism. But autism is still a disorder. Homosexuality is just a bit less tasteful to the normal, average heterosexual person.
Still doesn't keep it from interfering with the "normal state of being".
Which is, to use your genitals for their intended purpose of procreation.

It's not something you can pick, either.

You can't, but would you if you could?

I can hope and wish and want to be sexually attracted to women, but I won't be.

Oh you can certainly do the stuff they do. IF you want it so much, it might just become reality in your mind.
Really a weird person you are.

Humans want to pair up, we want company.

This is not a matter of pairing or company. Marriage is the foundation of society and the institution of family.
Homosexuals are not, and were never a part of this.
