Yes, I understand that but if what is needed is a group of people that have a certain set of behaviours (silence, or dancing, or talking about science), a religion is not needed. Joining a religion just because the way people meet is a bit too much, no? You also need to take in the whole set of religious stuff.
I completely understand that some places bring the kind of inner peace someone needs. I like to sit in churches to think because they are nice, cool and silent. I aml also an "active" atheist and these things do not clash. It is just that churches in my country (France) are great places for this kind of meditation, but it could also be a Buddhist temple or anything else not related to religion.
