@Julkorn:
Alright, I will accept that there is a possibility of disagreeing with homosexuality without discriminating against them.
Let me give another example: an employer dislikes homosexuals, and therefore either outright rejects every homosexual job applicant, or at least expects them to compensate for their sexual orientation with superior performance. What should the law have to say about this? Should it penalize the employer for discrimination, as he is clearly putting homosexuals in an inferior position in the job market? When there is lack of jobs, the job applicant cannot just endlessly search for another employer.
How about the Earth being a pancake in the center of the universe, then? Do you believe in that?

Homosexuality doesn't harm anyone, that is a valid and important point. This is a major reason to accept homosexuality.
With regards to incest, children being born out of sexual act between close relatives tend to have more problems than others, ie. health issues, lower IQ etc. This is a strong argument against incest, at least if it has the goal of producing offspring.
That said, I don't think incest is evil. My argument against it is purely a practical one.
