Some churches engage in business, perhaps by owning properties they rent. Some of these churches have evaded taxes by not reporting their business income. Some decades ago, a Dayton, Ohio, church was found delinquent and had to pay.
The question here is, Should atheists push for taxing all church property?
I fear politicians will find justice less important than the protests by churchgoers.
Because winning experiences are better for morale than losing experiences; let's choose efforts we can win.
