Oh bullshit. A sexual relationship between consenting adults is completely different than a relationship with an individual who cannot, as a legal matter, consent to it.
You can say that, and actually hope for that, but the door is open for legal challenges now.
People wanting to have polygamous relationships, marry inanimate objects, water moccasins, etc...
Rational human beings would agree that these things should be thrown out of court,yet.....
May I introduce you to the 9th circuit court?
You or I can't really know what may, or may not, happen next.
