Debate in the new millennium, part 1

From at least the 1960s, post-modernists began a protracted battle to change the nature of debate so as to ensure outcomes.

It has come to be called "shouting down."

It began with the Civil Rights movement in the 1950s in which peaceful, non-violent means were used to move the question of civil rights for Americans of African descent in the United States. (There is a good argument that it began with Gandhi in the fight for Indian independence from Great Britain, and its seeds were sown in the American and French Revolutions and the writings of the American Transcendentalists, but I'm looking only to contrast current movement with post-modernism.)

"Shouting down," as a form of argument, is just what it says it is. If someone disagrees with you, you shout until they give up, then you declare yourself the winner. As often as not, you can make it appear as if you are correct, though no actual debate was held.
