Thought-Experiment.
Imagine you are a taxpayer and the municipality you pay taxes in has a tradition of doing x. However, x does not provide any basic/fundamental right and it is something with which you disagree. Do you think the municipality ought to refund a portion of your taxes if they continue doing x? If there are enough taxpayers that disagree with x, do you think it would be prudent for the municipality to just forego doing x?
Now, since many do not like to think abstractly, build a few iterations of this problem, and in each one replace x with 'Christmas', 'Ashura', 'Diwali', etc. Are you willing to have your tax dollars fund those celebrations with which you disagree?
