The more broader problem being the Bible and bible literalism and just stinking religion in general.
True, but there are many valid way to interpret the bible that are different that the JWs way.
Many Ex JWs would argue that the JWs way are sometimes completely erroneous when looking at the context or when looking at other passages.
And don't forget that the NWT is a biased translation.
Examples:
Women appointed to positions in the congregation could be substantiated with the Bible.
Shunning could be dealt with differently and shunning disassociated persons was introduced to stop people from leaving, not because it can be substantiated with the Bible.
There is strong indications that JWs stance on the blood issue is wrong in regards to the Bible.
So this man could have freed himself from the JW dogma and still kept his beliefs like many Ex JWs do.
