Most people don't want to know about one's religion, in my experience. Just like I wouldn't really want to know about my friend's transition to Islam, Protestantism or Hinduism or literally any other religion. Mentioning it to people is awkward and doesn't help anyone. I have been more open about my spirituality recently but make a conscious effort to keep it toned down, depending on who I'm talking to. I'm not here to proselytize, I'm here to live my faith and that is mostly a very, very personal thing.
Then again, if anyone asks and is open to listen I'm happy to talk about spirituality.
