Just a day after voters decide between President Trump and former Vice President Joe Biden, the Supreme Court in November will hear a case expected to set the tone for future clashes between gay and transgender rights and religious freedom interests.

The case, Fulton v. City of Philadelphia, will determine whether or not the adoption agency Catholic Social Services must comply with Philadelphia’s allowances for placing foster children with gay or transgender parents. The agency, run by the Archdiocese of Philadelphia, sued the city in 2018 because the city’s rules force it to violate Catholic teaching. The court took up the case in February, and, after the Trump administration filed a brief in June supporting CSS, Fulton is becoming a central point of friction in sexuality culture wars.
