Blackmun's creation of a 'privacy' clause, in the 14th Amendment, is what all of these groups use to hide behind. This same phantom clause helped create the Roe v. Wade decision and many others.
It is the whole 'living constitution' idea that was the greatest success for the left. They have used it to undermine every other article and amendment since. Hence the 10th amendment is dead, the 1st amendment is not even recognizable: Freedom from religion, rather than freedom of religion / Freedom of expression (burn the flag, pee on the cross), rather than freedom of speech.
The next step is to codify freedom of 'speech'. It's only free if politically correct. Their next target is to render the 2nd amendment to apply only to Government sanctioned bodies: Military, police, etc.
The point of my tirade is this: it is too late to go after these groups with legal action, the courts have already sanctioned what they do and are filled with sympathizers to their cause.
Our only hope is to elect right thinking politicians, who will nominate and install judges who make decisions based on the actual wording of the Constitution, not on some fable of intent. Then we can work to overturn many of these past decisions Beyond that is a step that none of us really want our children to live through. One civil war was enough.
What do you mean "next target", these types have been asserting that for years. They even have the 9th US Circuit Court in their corner on the issue.
