The more WT bangs on about stuff it knows nothing about, in this case tolerance, the more pressure it puts on individual JWs to toe the line with regards to adopting intolerant attitudes towards non-jw people.
The more intolerant individual JWs become towards those on the other side of the cult compound the more psychological discomfort it will produce as their individual conscience struggles to reconcile the JW attitudes in their everday life.
Because, let's face it, trying to incorporate your JWness into everyday life is like trying to jam a square peg into round hole - regardless of their fairytaly ending videos, it just doesn't work. The more individual JWs that feel this uncomfortable mismatch of intolerant ideology with workmates and classmates the more JWs might actually start to wake up.
Or, maybe I 'm just a crazy optimist.
