This might be the whole point of this rant - the leftists would have us believe that the Constitution is outdated.
Of course, it is implied that they are the only ones who are enlightened enough to decide what parts are outdated. Their liberal education (isn't that an oxymoron???) obviously didn't teach them that there is a mechanism for changing the Constitution - it's not by concensus of some self-exalted group of liberals, but by agreement of two-thirds of both Houses of Congress and two-thirds of the states.
