The Supreme Court cannot repeal amendments. Do people know civics anymore?
We know civics. We also know how government abuses its powers.
SCOTUS can IGNORE laws which violate the Constitution and has been doing so for some time. Look at Article I, Section 8 and compare it to >80% of the Federals laws which have been enacted. Congress has no authority to pass ANY gun control legislation, but NFA 1933, GCA 1968 still stand. AWB 1994 sunset in 2004, or it would still be with us.
They can re-interpret the wording into oblivion. “Well-regulated”, “infringed”, even “the people” have new definitions (to wit: “licensed subject to micro-management”, “limited, reasonable restrictions excepted”, and “government agents acting on behalf of the subject population”) which are widely accepted, when applied would render 2ndA meaningless.
