Answer to Question 1
The questions might rather inspire us to consider if religions just need to be updated. This will raise issues like those of Question 3 above. Again, for conservative reader of the Bible or the Koran (see I Cor 14:34; Sura 4:34) or the Laws of Manu, this might be challenging. The closing question about how one decides which bits of a religion to update is challenging indeed. Specific examples might ask if a religion must update its view of women's roles, but not update its views of sexual morality or consumerism or miracles.
Answer to Question 2
You will probably sense that being moral is not the same thing as being religious, having, for example, the intuition (or the self-defensive insistence) that one can be a morally good citizen without being religious, and the equally defensive idea that many religious people are not necessarily very good.
