The excessive deletion needs to end

I take it you have never waded into a topic area of nationalistic conflicts, so you've never experienced the spammage of articles on massacres, terrorist attacks, and analogies between bad guys X and Y, never mind the WP:COATRACKING of barely related articles. Deletion requires consensus, so filling wikipedia with propaganda is quite easy when there are two reasonably-sized camps, so the (garbage) content accumulates! Everybody wins, right? (Should the sum of all human knowledge include all propaganda?) Of course, nobody who understands the Wikipedia editorial process would ever bother reading that type of article, but the general public doesn't know, although the saving grace is probably that Joe Public doesn't care much about such topics either.
