“St. Isidore’s application makes clear that it plans to discriminate in admissions and employment. The government should never fund discrimination. No taxpayer-funded school should be allowed to turn away teachers or students because they are of the ‘wrong’ religion, or have a disability, or are involved in a same-sex relationship, or have a gender identity different than was assigned to them on a birth certificate, or simply become pregnant. Religious schools – like houses of worship – should be funded through voluntary contributions from their own membership, not money extracted involuntarily with state taxes from members of a religiously diverse community.”
