That is false. There is such a place.

The Religion Group is not one of the safe haven groups, it is true ( "often" does not mean "always" ). However, the SOP of the Interfaith Group is as follows:

A safe haven that provides opportunities for people of all faiths, spiritual leanings and non-belief to discuss religious topics and events in a positive and civil manner, with an emphasis on tolerance. Criticisms of individual beliefs or non-belief, or debates about the existence of higher power(s) are not appropriate in this group.

Gil knows about the Interfaith Group and its purpose, but he prefers to post here instead.
