That depends. I have donated to Religious missionary work publicly, that could be seen by an extremist of any other religion who sees this as a zero sum game as anti their religion. But I don't bring this up in work because that is uncouth and not what my job is about, and would expect the same from co-workers. Eich also didn't donate publicly, this was dug up and then foisted upon him. If someone were to dig through records they could find my donations and party affiliations, which is what they did to him. He was being professional, they were the ones that were taking his private views and forcing them into the public sphere.
