Old fashioned bumper stickers are the medium of choice in this war of ideology taking place in laid-back Ocean Beach (OB), in San Diego County. OB has long been known as a liberal, safe and friendly haven for the homeless.

Compare the two bumper stickers. Both welcome people to friendly OB. The brown one says "Don't feed our bums" and was made by a local smoke shop to deal not the homeless they say, but the more aggressive panhandlers: 

"It isn't about the homeless...it's about the bums, the trolls that we deal with day in and day out, they get angry at you if you don't have spare change, they urinate in your doorways, graffiti on the buildings, it's terrible." said Denise Prigmore, an employee at The Black.

Many OB residents were angered and felt that the message portrays them as intolerant. Look what was created in response, by San Diego's Regional Task Force to End Homelessness.

Ideology and personal beliefs about homelessness aside, I see all forms of separatism, prejudice, and racism as a market segmentation issue. It involves dividing based on differences and uniting into subgroups based on similarities. Even good ideas like segmentation can be put to bad use. The positive segmentation challenge here is to distinguish between the "good" homeless and those that cause unnecessary harm and damage.
