You should definitely talk about it— like everyone said she should be able to put her own views aside. That is in fact her job. If she gets visibly offended and projects those judgments outwards then that is cause for concern.
All of that being said, you also should definitely after you bring up the topic, tell her that you didn't want to talk about it with her. And then basically say why you didn't want to talk about it with her. That could lead to a whole other conversation about people-pleasing but also hopefully to something along the lines of you not having to worry about that with her and maybe working on leaving those people-pleasing concerns with other people.
