Driving is a privilege. 1. Marriage is a right. Go and be ignorant no more.
1. False: polygamists still can't marry. Nor can a brother & sister. Marriage is STILL a privilege allowed to some but not all.
And that privilege is not defined in the US Constitution. So, by lawful default, it is the states who define it. That lawful delegation of powers was breached in Obergefell last Summer. And worse, it was breached to create a physical defect to children who not one serious lawyer would argue "have nothing to do with marriage" (for example, consult a divorce court on children's rights in marriage). Gay marriage by physical defect cannot provide either a mother or father. And this condition binds all children involved away from either a mother or father for life by contractual term.
You do not find this in single parents...they still can marry and often are seeking to do so for help, comfort and tax breaks...and for the best life for their kids with mom and dad. Divorced parents both mom and dad still see the children... Not so ever for children caught up in "gay marriage". There is a particular kind of prison that allows no father or mother for life.
