Yea I've seen this as well, I think it's hard once you leave the JW's to grasp, initially anyway, there there is a god outside the bible. It also appears to be difficult to let go of the "false religion" mindset. By that I mean after leaving the dubs you still consider any other religion to be bad w/o actually learning about them or attending their services to see for yourself.
For me it was babysteps...first letting go of the bible, then realizing there was a god and/or gods the might exist outside those parameters and then learning about and attending other religious services to let go of preconceived ideas about them. There is a great big wide world of interesting religions/faith based ideas and it's actually kinda fun to explore them. Expecially given the fact you don't have to embrace any of them fully this time around.
