"Newsflash", the entire point of constitutions that enumerate rights is that fundamental rights and freedoms may not be abridged even by majority decision.
If a Supreme Court strikes down a majority-passed law limiting free speech guaranteed by the Constitution, that's democracy at work.
If they can't be abridged, then why do we have amendments?
And no, that would be the courts at work, which may or may not be beholden to the whims of other political figures.
