Interfaith service to be held at the Democratic National Convention: Should atheists be invited?

Poll question: Interfaith service to be held at the Democratic National Convention: Should atheists be invited?

There is a movement afoot to have an interfaith service at the Democratic National Convention. It is to be lead by Pentecostal minister Leah Daughtry. The fly in the ointment is that she received a letter from a secularist group asking if any atheists groups are going to be invited to the service.

So the question is put to those here. Should atheists, a significant percentage of the DNC, be invited to the interfaith service?
