I think the mindset of that sign is to drive away homeless people that would turn their community into another San Francisco, L.A., or Seattle, where people poop in the street, crowd the streets with homeless camps, shoot drugs in the street near children and schools, and where the mentally ill homeless routinely assault normal people in the street.
The homeless in these places aren't merely impoverished, there's an overwhelming element of drug addiction and/or mental illness among them.
I saw a small business owner in San Francisco interviewed about a year ago on Fox, and she says she needs to arrive at her small shop about an hour early every day, to pour bleach on the sidewalk, and hose away the urine and feces from the night before. Every single day.
So yeah, I can see where people wouldn't want that setting up camp in their neighborhood.
