SO I assume that now a man can marry his own brother? There is no reason to not let a man marry his own brother since they cannot have any gene defected children together.There certainly has never been any specific law barring a man from marrying his own brother. SO now that that is legal they will have to repeal the limitation on marrying your own sister as well.They did pass those limits because people did try to marry their own sister/mom/daughter obviously. Well now they will have to allow it . They cannot alllow a man to marry his own brother but not his own sister. That would be discriminatory. If a father and daughter want to marry who the heck are you judgemental pricks to say they can't?
