The Constitution is an ancient and generally deprecated document in light of far more informed and recent documents as the constitutions of Europe. We would be in a similar situation if we looked upon the Framers as fallible men as ourselves and it as a fallible (and correctable) living document. If the Constitution was properly cared for over its lifetime, we could be moving forward, not backward.
I am saddened by your confusion of opinion with fact. Look at statistics and you will discover that your statements are antidemocratic -- and arguably anti-American. It would be easy to say that I'm 'just reading the statistics to support me', but that false counterargument has gotten really old.
Judicial review isn't constitutional. Are you questioning it? In fact, much of the Supreme Court itself is extraconstitutional, and the Senate so skews representation per populace in this country that little (red, uninfluential, &tc) states can influence the ways of the country disproportionately. States do not deserve representation -- they are geopolitical units. People do.
And yet, where are women in our government, for example? And besides, I can't see why so few can learn addition -- cutting taxes gets us nowhere, almost as nowhere as attrition measures. Raise taxes already! Reduce rampant income inequality in this country and we might get somewhere.
Also: don't argue for States Rights. I don't need to tell you why.
tl;dr:
Read the Constitution.
Learn more about the constitution.
Come up with your own words.
