The meaning of the Constitution was changed well over 100 years ago. Its ridiculous for you, or anyone else, to act like the sole incident of the SCOTUS knocking down an irrelevant, hardly-ever enforced law somehow "changed our form of government" or "changed the meaning of the Constitution" considering 100+ years of SCOTUS decisions and un-challenged federal legislation that is in place. Its hilarious, that considering FEDERAL usurption of rights like Social Security, the progressive income tax system, federal gun laws, federal drug laws, environmental laws, trade treaties etc, that people would claim this one decision has destroyed America. Frankly, people who make such arguments look like knee-jerk reactionists - not unlike the "left" who we make so much fun of.
You have a very good point, though, that this is not a new fight.
Buck up, defeatism 'never won fair' right.
People who oppose court usurpation are not your enemy, even if they do so on a matter you think not important.
