What does your comment have to do the article above?  It sounds more like 'how many angels can dance on the head of a pin"?  

In today's society, would people attending Mass have badges on them stating "I am an Atheist" so that everyone would know that they are atheists?  

And since the Eucharist is to be a PARTICIPATED liturgy---WOULD a priest be celebrating [not just mumbling words---which is "saying Mass'] the liturgy if he KNEW that he was in the presence of ten atheists?

Comment on the article, please, and not in trying to trap people in your pharisaical, hypothetical statement games.
