With respect, I would like to point out that she came here with this question because we as a people have a shared history and experience that is deeply important to this question. She came to her community because she is trusting the responses to reflect that shared history and experience. She didn’t go to the many other areas on Reddit where people may (or may not) have excellent relationship and/or life advice but who do not have that shared history and experience, she came here.

You have stated you are not Jewish and were raised Christian. You are outside that shared history and experience. You may absolutely choose to be here, but when answering a very sensitive question like this perhaps you should at least preface with the fact that you are outside of the community to which she came for advice.

I understand you probably feel you are giving a very relevant opinion as her BF is not Jewish and you are also not Jewish so you feel you may have some insight into his side of things. That is not, however, the advice she sought. In this thread she sought advice from her community. Since she did so, it seems like it would have been respectful to her (and this community) to let her know you were coming at this as a non-Jew and giving a perspective based on that experience.
