There seems to be less respect for consensus because there is less respect for consensus. This change is not good or bad per se — it has simply made agreement a scarcer commodity across all issues of public interest. The erosion of controls on public speech have enabled Birthers to make their accusations against the President public; it also allows newly-emboldened groups — feminists, atheists, Muslims, Mormons — to press their issues in public, in opposition to traditional public beliefs, a process similar to gay rights post-Stonewall, but now on a faster and more national scale.
There’s no going back. Journalists now have to operate in a world where no statement, however trivial, will be completely secured from public gainsaying. At the same time, public production of speech, not just consumption, means that the policing of ethical failures has passed out of the hands of the quasi-professional group of journalists employed in those outlets, and has become another form of public argument.
This alters the public sphere in important ways.
