1. I don't find discussing one's faith in public offensive, I find it rude, unless you are among those of a similar faith. There are many religious beliefs, not all agree on every detail. So avoid hard feelings or criticism or protests. As the Constitution demands, "separation of Church and State", but "freedom of religion".
2. Gays and minorities can discuss whatever they want among gays or minorities. However, if they are speaking as Speaker they should keep the discussion on work related topics.
3. I'm more considerate of the beliefs of others.
