This is a very difficult concept to follow, but 
if you bear with me, perhaps you can grasp what I mean.
Just because I can tell you what someone else thinks
does not de facto mean that I believe it myself.
It is possible for me to accurately describe
the WC's SBT even though I disagree with it 100%.
When criticizing a position it is important to state
it accurately so that we know what we are attacking.
If someone else tells me about something and I want
to pass it along to others, I try to keep the story
intact and not color it with my opinions.
