The city apparently has other groups that have such favorable rent agreements BECAUSE they comply with the thought control rules of the city manager.
In addition the city has said IF the scouts comply with teh thought control rule then they can keep the building otherwise they have to pay a “penalty” to stay.
IOW, in another world “if you are a catholic you have to pay double because you will not convert to anglican and reject the pope.”
If you can show where the city holds them to different standards than those they're holding the Scouts to then you have a case.
