Your post seems to be misleading. Both rulings focus on selling goods to non-members, which seems rightfully taxable. This discussion is about taxing churches/religious organizations in general on all revenue/income (ie. tithe, donations, membership fees, etc). That would very likely be unconstitutional, as that would limit the organization's ability to assemble and practice religion.
