Obviously I have been forced to respond to the recent incivility. I will not guarantee that the person involved will not return to our on-line community. In fact I made it clear that I will consider inviting the person back if that could make sense based on contrition and understanding from that person.
We are not a social work group. However, if we can succeed in moving people toward social values that work for them and the rest of society it is worthwhile spending some time in responding with our best wisdom and compassion.
