Personally, as a Latin@ Catholic theologian who is una nieta de inmigrantes, I share your passion for justice for all migrants. I am particularly drawn to the attention you bring to cities in your theologizing, probably because I identify as hurban@́, Hispanic and urban, thanks in part to my New York roots and distinctive Bronx accent.
I may never be able to understand the "purpose" behind God "allowing" this tragedy.
