that's a fight that could easily go to the supreme court, and with the recent additions to the court, it has about a 50/50 chance of passing.
there are all kind of first amendment issues to be dealt with, and a long battle about the definitions of words and their application to different groups....and you have a fight to get it past your city. once you get it past your city, you have to keep the momentum going and get other cities involved....
which would be easier if you had some kind of organization.....i'm sure a lot of effort is being duplicated, and some things that should be getting done, aren't....because no one is aware of what anyone else is doing...and no one is calling any shots.....you got lucky that your mayor is sympathetic to your cause, and doesn't want to upset his constituency...there are a lot of other cities where they administrations won't be sympathetic...and the constituency will be against you....what do you plan to do in those cities, to bring the unwashed masses into the light?
