Ok, let's look at your answer more closely.
Paul said not to even eat with a man that was once called your brother - Paul added his own opinions to nascent Christianity - Jesus didn't say this. This might be why the GB orders JWs to shun disassociated people.
I would also indicate that Jesus stopped his association with Judas when he excused him from the lord's evening meal before his betrayal of the Christ - false equivalence. Jesus chose to stop associating with someone who he knew was going to kill him. This has nothing to do with JWs shunning child abuse victims who have chosen to disassociate themselves from Watchtower.
ultimately it is a choice that someone makes if they want to shun a person or not - this is a choice that JWs make with the threat of disciplining and shunning hanging over them, thanks to the GB. Ultimately, it's a choice under duress.
I have never known someone who was DF for speaking with someone who was DF or DA - that obviously doesn't mean it doesn't happen. Look up what happened to Ray Franz.
I may be living in a fantasy world - no comment (!)
I feel that one who is DA is just as someone who is DF - really?
In the context of this thread, we're talking about the ARC and victims of child abuse who disassociate themselves. These are surely not 'just as someone who is DF', right?
"the reason why we shun disassociated people is because the Governing Body tells us to" - this is it, in a nutshell.
