Peace Month is an excellent challenge. It is also a great way to focus attention on problems in our world and the gaps between people that remain unbridged. Thus far, daytime fasting is not a major problem or a huge difficulty in itself, but it is tricky to handle in social relationships. Food & drink are a key part of so many social activities. People living in communities where many or most fast for Ramadan have differing challenges than people living in places where those fasting are a small minority.
Further, the goal of Peace Month is peace. - building links between people, between faiths, between nations. But Peace Month fasting might misfocus attention on the fasting individual. Simply instilling a 'holier than thou' image is unhelpful. How can we effectively highlight peace?
