Okay, so you admit that employers pull FICO scores, but that they then just go "well, we've seen it and now we won't use it in any way to influence any decisions whatsoever"? When why are they pulling it? That doesn't make any sense. It's a very safe assumption that if they're pulling it, they're using it for some reason (either current or future) relating to their decision to continue your employment.

As for renting: Do you have any examples of cases in which "religion" was used in conjunction with credit scores to successfully argue discrimination? Because I believe it's pretty standard to pull credit checks on renters before they sign a lease, and again, I'm going to (not so) boldly assume the landlord is then using that in their decision making.
