Since we have so many people thinking homosexuality is suddenly acceptable, then what reason do we have to deny incest the same representation?

The bigotry of this statement is just overwhelming. It suggests that homosexuality has ever not been "allowed" or "acceptable" by a proper moral or legal system. It is not the place of law to have any say in any transaction between adults that do not involve the rights of others. And a sexual preference of gender in no way translates into a lesser moral state. It should disturb everyone how low an appeal to emotion this is; attempting to play off of the perceived negativity of incest to make a point against homosexuality.

Depends on whether there are any rational compelling arguments against it.

I have not found a compelling argument against incest, so for now I see no reason to disallow it.

In some cultures, incest is the tradition in order to preserve the royal lineage the clan holds dear. If it concerns 2 harmonious couples and each are ready for the commitment without causing further chaos then yes, it would be alright.

For years, both have been extremely taboo given the traditonal act of sex. Both will occur whether legal or not, so as long as two individual are consenting adults, there is no harm.

I doesn't matter whether it is allowed or not. It will continue to happen.

If it doesn't negatively effect me... I don't care.... get it on with your sister.

yes . we are not dictators to tell people what they should or shouldn't do

If we allow homosexuality it would make us hypocrites for not allowing incest relationship. Love is love, someone would prefer to be with a family member whoever it is.

Birth defects? The risk of birth defects is also real with women over 40, do we just tell them that they are not allowed to have children?

When allowing incest we should primary look at the relationship part of it. The potential risks can be talked between two consenting people who do incest not the government.

Not all incest leads to child birth. Plenty would want to take part in incest but without the risk, but they still want incest. You can wear protection and do other things that would avoid getting pregnant.

I do not see how it would ruin the family. If let's say you have sex with your mom, your mom being your mom does not disappear you will still see your mom as your mom regardless of the amount sex you have with her.

And in some cases the sex might even make the relationship between relatives stronger.

Like in the traditional view sex is seen as the ultimate showcase of love. Basically that one would only have sex with someone one loves. This would make incest completely rational as you are basically showing how much you do love your relative.

Also incest is already allowed in many countries, even if it is frowned upon. It is more likely that incest would be legalized where it is still illegal than to deny it.

Being disgusted is not an argument but your view. I might hate gabbage but I am not going to make it illegal. I think smoking is really bad for you but I also believe that you are responsible of your life not me.

If you want to engage in incest it should be allowed as long as both parties involved agree to the act.
