i5guy, the point seems to have sailed over your head like a javelin in the Olympic decathalon.  All of the things you mention indicate a lack of respect on the part of the homeless people you encountered, and my point was that a mutual respect would preclude those types of behaviors, as well as preclude a "kick them all down the road and who cares" mentality on the part of business and home owners in Portland.  Given the numbers of the respective populations we're talking about, it's very admittedly a fantasy to imagine 100% good relations at any given point, but you can push back against feel-gooder suggestions like the original poster above without demonizing every and all homeless person or griping about how Portland offends the tenderness of your delicate sensitivities.
