Specifically, the new language says the RFRA does not authorize a provider — including businesses or individuals — to refuse to offer or provide services, facilities, goods, employment, housing or public accommodation to any member of the public based on sexual orientation or gender identity, in addition to race, color, religion, ancestry, age, national origin, disability, sex or military service.
The proposed language exempts churches or other nonprofit religious organizations — including affiliated schools — from the definition of "provider."
