No, the Congress is supposed to be the legislative body.  You are right that sometimes values are imposed on the states. When values are imposed, it is supposed to come through the democratic process--that is---people convince the law makesrs who represent them to pass laws.  

The problem is that the SCOTUS isn't supposed to be making laws.  If liberals love abortion so much, fine.  They should try and persuade the Congress to legalize abortion.

The founders did not set up the SCOTUS to give people what they could not get through the democratic process.  That is the problem today--the liberals use the court systems to get what they cannot get democratically.

The paradox is you hear liberals say "This is what democracy looks like."  Except when it gives them a non-liberal result.  Then they want 9 unelected and unaccountable monarchs to impose their will from on high.  All of a sudden they don't like democracy.
