WNBA superstar Brittney Griner is taking a hard stand on the Religious Freedom Restoration Act in Indiana -- saying if the Women's Final 4 was in the Hoosier State, she would've BOYCOTTED.
Griner -- who's openly gay and set to marry her GF Glory Johnson later this year -- was at LAX last night when she told us, "If the Women's Final Four was there, I damn sure wouldn't have went."
She added, "I wouldn't want to be discriminated [against]."
Griner says she's happy that powerful people like NCAA president Mark Emmert have openly opposed the Indiana law -- saying, "It definitely helps. When people are quiet and don't say anything about it, it doesn't help. People think it's OK."
