Some go from believing everything the WT says, to believing everything apostates say.
I noticed this as well. Some people go from being JW to Mormon too. If people are going to look for justification of how they "feel" then they will do it regardless of their belief system. I think you finally get over it when you can recognize good and bad in the same sentence, and hav empathy for the people still trapped inside.
Then again, many even most of them, like that "trapped" feeling. At the end of the day we are all just people. I understand anger and bitterness in some peoples instances with no problem. They lose their wife, job, family.......I get it. It may not be healthy, and I hope they find peace, but its not like their anger isn't justified.
I tend to be more frustrated than angry, but that just the stage I'm in.
