I don't believe the constitution applies to what your community government decides to fund. If all your libraries and parks were paid for by the Federal goverment, then I think you'd have a point.
You are either missing my point or ignoring it and that is it isn't the government's business (government at any level) to steal from one group and pander to the other with the stolen goods. And, if you think that federal tax dollars aren't used by local governments to pay for some of the stupid stuff that they do, you aren't paying attention to the world around you.
