That's a widely shared view among more aggressive atheists. If and when churches enter terminal decline, tax relief policies may undergo an "adjustment"... despite the separation of church and state in the constitution, this has little bearing that Christianity was a moral bulwark at many levels, not just a doctrinal story... though buttressing doctrine was widely seen as a first order of defence against the "owl of atheism", a dreaded condition which got going in the late 18th century but really took off in the 19th , England that is. (having an aside chat here :) )
IMO all churches should be taxed
