If your morals and your beliefs are so weak that a little challenge puts them at serious risk, then perhaps they were not worth upholding in the first place.
Exactly. I have long considered the beliefs held by JWs as personal, are not truly their beliefs since most would immediately accept without question, a change to those beliefs if WT told them to do so.
There is an apparent fear conveyed that JWs in reading, hearing or considering anything contrary to that taught by WT, will cause them to abandon WT teachings. In this manner, WT is in effect acknowledging its teachings are weak and are not true. Individual JWs further acknowledge this when they fear and immediately run from anything which challenges 'their' beliefs.
