I have seen this happen at work,
During a referendum a couple of years ago, one member of staff had a discussion about why everyone must vote yes, another member of staff suggested that it was none of her business which way anyone else voted, (he didn’t, at any point, use the word no) and she, from that moment onwards, refused to speak to him again.
She also tried to put a grievance in with management, removed him from her facebook page, attempted to have him removed from a facebook group we are all on, (the group is used for roadwork updates) and made her mouth go about it to anyone who happened to be near, for the remaining 3 months until the referendum actually took place.
Religion and politics, don’t discuss them, ever.
