Indiana advances bill that would 'mandate discrimination' against trans people, ACLU warns

Wonder how Indiana's law would comport with the Constitution's full faith and credit clause (basically how gay marriage came about) when a transgender person born outside of Indiana but has updated their birth certificate relocates to Indiana. Birth certification is a power reserved to the states under the 10th Amendment. So, SCOTUS can't set an interviening rule about how birth certificates are to be written if a dispute arises between the states on this.
