I haven't had much of an issue. I do know that my brother does not want me present for Christmas get together between my sibslings and father because I am Jewish. I was not invited this year but that could be more so because my sister likes to keep me away from my dad (it makes her feel special). It's possible it was also because my brother did not want me there but he insisted to my mother that he didn't know I wasn't invited. But my siblings are strange and there would be issues even if I wasn't a Jew.
This is the only thing that has come up so far. I did think a friend was pushing me away because our religious differences but I figured out that was not true. I do think it's possible she would prefer I don't mention much about it in her home. She's very into the idea that demons inhabited everything (even objects like magazines or pencils) and has always thought her house was full of demons. So to her maybe talking about a religion that does not include Jesus will bring in demons or something? I don't know. Bee might understand this line of thinking better than I do. She's been involved in the same kind of chuches.
My friends reacted really well, actually. I never expected them to be so casual about it. Now of course we don't really discuss it so that might help. I don't discuss it with family either.
The only advice I can give is to give her some time to let it sink in, you know what I mean? People may need time to just think about it and get used to the idea. It may not even be that they think it's a bad thing, it's just new and different.
I have noticed that some conversion students want to argue or debate. I'd advise against it. If a good friend or relative tries to bait you, don't let them. It's perfectly okay to tell people you do not want to discuss emotional or controversial topics.
