Disgellowshipping isn't the problem as many who I have known to be Disfellowshipped have done something pretty bad, cheat on their wives, get girls pregnant then ignore them and split up families or start abusing drugs etc.
So many of these people are ones I would choose not to have close association with anyway. However I do not and can not for the life of me comprehend why such ones are totally shunned. Especially inside the kingdom Hall. The kingdom Hall should be the one place where we are ALL equal in the sight of God. And not having close association with a person doesn't mean you have to shun the with the extremist behaviour that prevails the congregations today π
