The legal status of too close familial relationships is a key stumbling block to siblings marrying.
Y'all have A LOT of work to do.
*sigh*
You are not listing nor do you give a damn about actual rights or equal access - something you have been falsely claiming to champion for years.
It was all about getting what you wanted and ignoring any actual impact or extension of the same. I am not surprised.
Try as hard as you might, you can't ignore that one is legal and the other is not.
There was no reasobable excuse to deny gays their Constitutional right to be treated equal under the laws in terms of marriage; whereas, there is a compelling reason to deny those who violate incest laws.
And the same could have been said for gay marriage.
That did not seem to matter though - did it. Try hard as you might, simply pointing to a law that is fundamentally flawed does not make a valid argument to allow the law to stand.
The standard remains the same.
Americans have a right to marriage- that is well established- just as owning a gun is a right.
States can deny Americans rights only when they can demonstrate a clear and convincing benefit to the state that denying such rights will accomplish- i.e. denying convicted felons the right to own guns.
Homosexuals were denied their right to marriage simply because of either their attraction to the same gender- or technically- based upon the gender of the person that they wanted to marry.
Siblings- and parents/children- are denied marriage under different laws. Perhaps the State would try to use some of the same arguments against incestuous marriage- such as 'tradition'- that didn't work and wouldn't work as an argument against incestuous marriage.
Whether or not there is an argument against mothers being allowed to marry their sons has absolutely no relation to two unrelated homosexuals are allowed to marry. Either the state(and anyone who is opposed to such a marriage) has an argument- or they don't.
And if the State has no argument- then the law shouldn't exist.
However- in court cases regarding gay marriage, incestuous marriages were brought up- and judges did point out how they are different from gay marriages- indicating that States likely do have persuasive arguments against incestuous marriages.
But if you think that such marriages should be legal- you have the same legal options as gay couples did who fought against laws they felt were unconstitutional- either argue to change the law- that happened in several states- or go to court to claim that your constitutional rights to marry are being violated- and convince the court.
