If it even existed in the first place; there are plenty of laws that expressly allow discrimination in deference to 'religious beliefs.'
Courts, & the Supreme Court in particular, are giving far more weight to 'christian freedom' at the expense of the rest of us.
Cases include recent PrEP ruling, insane football prayer ruling that willfully ignored facts, bathroom & sports laws targeting kids. crazy ruling on prayers in court.
Adoption discrimination (de-facto govt by transitive property. we have to stop outsourcing government to contractors, especially when it makes religious orgs the only avenue).
Upcoming ruling from CO which will probably allow even more queer discrimination.
that 'pressure to conform' is and has historically been one way, giving one class the legal go ahead to discriminate in the name of some skewed idea of christian ideals
