One of the biggest challenges of Tisha b’Av is finding the strength to feel pain that has had thousands of years to heal. For many people, the day ruefully memorializes our fallen temples, but for many non-Orthodox Jews, the loss of our temple is no reason to be sad. Perhaps this explains the dearth of non-Orthodox Tisha b’Av services. Why mourn for a temple if its absence is not considered a tragedy?
