text: You continue to ignore what I'm saying: Greece v Galloway in your own words, says that the city is not obligated to go outside its borders. Obligated means a burden, as in "city you MUST find religions other than Christian" which is not a legal burden to impose on the city.
  
  However the city must allow those that come to it OFFERING their religious invocation to have an opportunity to speak.
  
  This means the city can't be forced to seek out speakers from religions if it doesn't exist in their area, but if someone shows up offering/requesting to speak it is discriminatory to exclude them.
  
  KPB is substantively different because KPB is directly excluding even voluntary invocations from outside. That is the crux of why it fails the test of Greece v Galloway.
