Expect intolerance. People often
deny (block out, won't listen to, won't read, won't look a-) any contrary
ideas, opinions, viewpoints, or beliefs. Often people "frame an
issue" in one way, then later reject any facts which contradict
their pre-conceptions.("Don't bother me with facts, my mind
is already made up.") People often won't consider the possible
"rightness" of their opponents' Cause, or of their opponents'
legitimate needs and wants, or of their opponents' genuine fears and grievances.
