Hi anglise,
I live on an ialand that is about 90% catholic many are excommunicated, but none are shunned, that in it's self is the biggest differece. Plus they do not tell you that the only friends you should have need to be JW...... oops Catholic, they also do not tell their Parishners, that those that are Ex'd are apostates, or ones to be avoided. The Ex'd are just limited in what they can do in the church, and it is left to God to decide the rest. Unlike the JW's in that if you are EX'd (DF'd) you are doomed, you are not to be associated with, you are dead!! Avoid those ones, they are discusting people, they will die by the hands of the Almighty God Jehovah. Does that answer your Q?
