Normally this type of stunt is carried out by a candidate during the election year. In this instance we have a few activists, a term I use loosely here, trying to gain attention. What I find sad about their micro-jingoistic plan is that it will do nothing but hurt their neighborhood. If I am the Mayor, I slam these guys down hard. Show them who is in-charge and don't let them forget it. They are not going to vote for him anyway, so no need to use kid gloves. I would seek out some sane people in that neighborhood and snub every person who votes yes on this crazy notion.
The unfortunate and real fallout from this foolish notion will be some residents increasing their hate for minorities and the poor, and they will continue to alienate themselves from the rest of the city. When you let the fringe view points, and in this case they are based on racism and/or classism, you are going to rightfully get blowback. These 'activists' need to learn they live in Cincinnati, not Mayberry. If they want to live in a little rural town where everyone looks the same and nothing ever happens, they can move there. Happily, that place is a myth.
