There aren't that many Satanists in the world, but the far more common case is presumably people fired as soon as an employer found out they were gay. Note that sexual orientation is still not technically a protected class, though the EEOC will often take up for you anyway: https://www.shrm.org/resourcesandtools/legal-and-compliance/.... Many localities explicitly call out sexual orientation and Obama signed an Executive Order mandating non-discrimination in federal agencies and contractors, but the actual Civil Rights Act does not protect this and case law on specific suits has been wildly inconsistent about it.
