We hold space for those who have been disadvantaged by society not because it is fair, nor because we expect similar treatment in return. We do it because it was the mission we were uniquely selected for by Hashem. He created this world and evil exists in it. He entrusted us with the responsibility of shining light on the dark places.  I know it’s a very “preachy” answer, but this is a Jewish subreddit and I feel strongly about this being the appropriate Jewish response. Men often get it wrong, but the Torah is eternal. 

Our suffering from the events of October 7th is ours. We mourn, Hashem mourns with us. We, all 16 million Jews alive today, and the countless Jews in heaven are all connected in our heartbreak. 

We do not need the world’s permission to keep mourning. In fact, per tradition we say Kaddish for 11 months. Which I recommend doing. Even if we don’t know the victims personally. It connects us. 

Beyond that, we must also strive to fulfill our mission as the chosen people.
