There are no sound arguments as far as I am aware, you could prove me wrong by making one.I agree. I believe bestial relationships should be illegal for the same reason, but there are sound arguments to the contrary (just ask Agnapostate) and these arguments cannot be ignored simply because you don't agree with them.
No, I don't think it is entirely possible but as I said above, you could make an argument and we'll see.Legally speaking, it is entirely possible that a bestial relationship could garner the same Constitutional protection as a heterosexual or homosexual relationship, and pursuant to such a determination one could make an argument for equal protection under the law, e.g. state-sanctioned bestial marriage.
If the "state" is going to be involved in marriage then, yes.Once again, I agree, but the question is not whether polygamist relationships should be illegal, the question is whether or not they should receive positive recognition from the state.
Yes, I do affirm that consenting adults should be able to enter into a state recognized contract, currently called marriage, regardless of the race, creed, religion, sexual orientation or number of consenting adults involved.If you affirm the "right" of gay couples to marry under the equal protection clause then you must also affirm the "right" of polygamists to do the same; unless, of course, you're just a hypocrite who doesn't know the first thing about Constitutional law.
So, do you affirm the "right" of polygamists to receive positive recognition from the state in the form of a marriage? Or are you just another person who screams about "rights" and the Constitution when it suites their political agenda?
It's a pretty simple concept of equality, fairness and privacy.
