This organization (or something like it) has existed for quite some time. They originally stood as an organization that attempted to broaden societal perspective of freedom of religion through acts like establishing "Satanist" monuments where there were only Christian ones (https://thesatanictemple.com/pages/more-info). Another mission was to put emphasis on supporting folks who lack a religion. Notably, the DNC tried to target Bernie for not openly displaying his religion (https://liberalamerica.life/2016/07/24/dnc-planned-deliberat...).

This website looks somewhat different, in that it appears that they're trying to pursue a secular moral community. I'm not really sure that's a good thing.
