I find the whole "disfellowshipping" thing odd. Here's why.
Satan, the liar, and the very accuser of God Almighty, is given audience before God to irritate Job. Kill his kids, etc. Later, he tempts Christ, and Christ speaks to him without condemnation. Now this guy is a pure POS, but everyone heavenly is still talking to him and his cohorts.
When you think about it, who are we as humans to stop talking to someone we disagree with on trivial matters when Angelic forces, to include the Almighty himself, have not done the same with the most rotten evil asshole in the universe?
Seriously, THINK about it.
