A common argument that JWs use against fellow JWs questioning leaving the group is "where else will I go?".
Of course one doesn't have adopt a new belief before he dismisses his old one. As has been discussed on this board before, to do so is to simply rely upon a burning house argument (demand a person give you a new how before you leave the one you are in, which is burning down). Some leave the JWs by conversion to another system (i.e. a differant version of Christianity, Islam, Mormonism, ect), in this sense they base their decision not only upon the wrongs that are eaisly identifiable within the WTS, but also because of it's disagreement with the new system they now prefer.
I would say that after leaving the JWs I really haven't "turned" to anything in the most absolute sense because any belief or philosophy I entertain never holds the same kind of grip on my mind that the JWs ever did.
