Here are a few arguments, gleaned from the current thread (paraphrased by me, and hopefully not completely misunderstood):

Reproduction should not be the only purpose of a marriage.

Rather, there can be a true bond of love in a relation.

Whatever I consider natural or unnatural is a subjective opinion.

The fight against homosexuality is a result of narrow-mindedness, intolerance, etc.

I don't have the right to tell others what is right or wrong.

Imposing "correct" sexuality on a minority who believes otherwise is unfair.

The points of view of the psychiatric association - doesn't apply, since, AFAIK, they didn't make a similar statement about bestiality, or about incest, for that matter. Of course, they might do so, eventually.

Your sexual orientation should be your personal choice - I think I am the only one who mentioned this in this thread, but I understand this is a fairly common argument.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
