> The lawsuit cites another post from another hiring manager that said, “If you express a dunderheaded opinion about religion, about politics, or about ‘social justice’, it turns out I am allowed to think you’re a halfwit… I’m perfectly within my rights to mentally categorize you in my [d*ckhead] box… Yes, I maintain (mentally, and not (yet) publicly).”

It's definitely illegal to discriminate based on their religious beliefs. I'm thinking the discovery process is going to find a lot of legitimate issues, if the the lawyer bringing the suit has already found stuff like this. Maybe the lawyer was using this blacklist stuff as a way to get more information and find bigger problems.
