I’ll gladly explain. When the Supreme Court was created, its intention was to settle legal disputes between individuals and states. It would apply the dispute to law and the constitution and act accordingly.
After Marbury v. Madison, they granted themselves the power of judicial review, which is the court’s ability to interpret and strike down passed laws that violate the constitution. While this had been discussed in the Federalist papers, this technically wasn’t a power given to them by our constitution, but given that it would lead to an ultimately stronger system of checks and balances, no one disputed that the courts should not have this power.
However, it only works as a check to legislative and executive action if the courts are apolitical and are not influenced by outside pressures. That was the idea behind appointments being for life, but unfortunately it wasn’t enough to prevent partisanship from entering the system. Now we see liberal and conservative justices split on several issues that should be constitutionally clear, and it’s always amongst party lines. And I’m not blaming either political party in particular as they both do this.
So to get the system working as intended again, we would need a clean slate of justices instead of stacking the Supreme Court to accomplish part agenda goals. I know that will likely lead to decisions that I will disagree with, but it will be okay given the system is less corrupt.
Now I realize that a clean slate of justices is pretty much impossible to except much less carry out. I know that it won't happen. But as long as we’re on the topic of corrupt justices, we should impeach those who have been shown to take bribes, like Clarence Thomas has. And if you have evidence of other justices taking bribes, regardless of their affiliation, add them to the list of impeachments.
You asked for a manifesto and here’s an abridged one for you. Please do tell me how this exercise of free speech and expression is a “threat to democracy”.
