I am on Joe's side. it's clear he actually knows these folks who are homeless from consequence or by choice. However he has probably not been one yet. We are all one fire away from homelessness in the short run.
Virtually everyone who has posted here have profound humane attitudes toward the homeless.

My interaction with the homeless runs the full spectrum of providing food and shelter to not giving a cent. People who advocate politics of the mean and cruel are blind to their own future. The social contract to care for on another is lost on them. Curing their blindness takes a lifetime in some cases and for some of the most wealthy, forever.
