I was talking in particular about the use of profanity in a working environment, of course.
I do not know what you are reading into those emails but speaking purely objectively, there is remarkably little content in them to go off of. It could potentially have to do with Bernie Sanders in the Kentucky and West Virginia primaries (which were in early May), but that seems somewhat unlikely given the timestamps -- the West Virginia primary was only 5 days after the email was sent, which is almost no time for one to ask the question, get whatever answer, and launch a smear campaign. It could also be not about Sanders at all--WVA is an odd way to refer to West Virginia when WV will work as well, and the name "Sanders" doesn't appear anywhere in the emails themselves.
Even if it's about Sanders, the email doesn't even say whether the guy is rooting for or against Sanders: it could just as easily be "Hey, I heard this rumor that Sanders is an atheist, can we get someone to ask him so that he can squash that rumor like a bug?"
It doesn't strike me as a "civil rights violation" to ask about someone's religious views. I mean, maybe the US people not voting for politicians based on their religious affiliation is a larger civil rights violation that you fear will be triggered if this question is asked, but that seems like several steps away from a sure thing, since it's quite possible that Bernie will play a different political card.
