For Americans at least, that mentality has evolved over time as we further distance ourselves from the Constitution and its Amendments; trying our best to ignore their very clear limits on the capabilities of each branch of government. In today's American society, a diverse (and often mutually disagreeing) set of groups see the limits set in the Constitution as quaint and outdated, too inflexible for the modern world. Some see the Fourth Amendment as unreasonably limiting the effectiveness of national security and law enforcement. Some see the Second Amendment as a relic of a more violent world. Some see the First Amendment as intolerant of intolerance. Some see the Ninth and Tenth Amendments as needlessly frustrating the federal government's ability to quickly "fix" problems.
Today, I find the Constitution—and more importantly, those who bring it up in polite political conversation—to as often as not be marginalized as "extreme" or, worse, comedic. There is a rough equivalence of "Constitution" with "Murica" (or similar slang insults depending on the point of view of the person who sees the Constitution as an irksome trump-card used to roadblock their agenda).
As someone who believes the Constitution was a work of genius that facilitated this country's ascent, I also feel that for all our modern failings, the Constitution is one of the remaining bulwarks helping keep us afloat. I am sad when I see it attacked so successfully and relentlessly by myriad disagreeing groups. Those who seek facile, overreaching, and quick government solutions to complex problems routinely want to ignore the limitations set by the Constitution, not realizing that deliberation and careful thought were and should remain a cornerstone of our governmental model.
