This is good. This is what I imagine most people would think, myself included. I'm not sure it would be so easy if my six-year-old son's best friend asked if he could eat with us. I've lived in my neighborhood all of my life. I've known some of my neighbors for 35 years. Would I (could I) drive them away with threat of violence if they were in trouble. It seems to me that sort of lack of community is what will lead to a collapse. Perhaps I'm just a bleeding heart liberal (or something), and it might be obvious if it ever comes down to it, but for now it's an ethical problem for me.
