Complete bullshit. There are countless interpretations of the law made by the courts that act to define what is meant. This one didn't come "out of thin air", that's preposterous. I suppose you believe gay marriage, or interracial marriage rulings "came out of thin air" as well. Again, bullshit.
An activist court is one who, before confirmation, claims Roe v Wade is settled law and then, after confirmation, votes to overturn it. Not just activist, deceptive activism.
These people did nothing other than exercise their rights to leave, peacefully, and make a point. That you are up in arms about this demonstrates how far right you really are, despite your claims of being more moderate. You are just as dangerous as those on the fringes.
