Well, it isn't the "congregation's" disfellowship order since I doubt the "congregation" had any say in the matter. Maybe back in the 1950's JWs followed the scriptures and put matters to a congregational vote. But nowadays three guys not chosen by the "congregation" decide stuff in secret.
That whole JW lust for Mosaic laws is what should be put to death. If it doesn't apply to Christ, it is "old light". The problem with JWs is that their leadership has continuously refused follow Christ.
Matt5: [44] But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you, [45] that you may be children of your Father who is in heaven. For he makes his sun to rise on the evil and the good, and sends rain on the just and the unjust.[46] For if you love those who love you, what reward do you have? Don't even the tax collectors do the same? [47] If you only greet your friends, what more do you do than others? Don't even the tax collectors do the same?
I don't see anything there about rock throwing at "enemies".
