Why shouldn’t schools pay water charges?
After all, the bishops, rabbis and mullahs will be very quick to remind you that the State doesn’t own the schools. They’ll be very quick indeed to remind you that the schools are in fact owned and run by the various religious denominations, and not by the State (though the State pays all their costs, including teachers’ salaries). They’ll remind you till you fall down from exhaustion what a wonderful service they provide to the State in running these schools (even though all the teachers are provided by the State).
What they’ll be slower to remind you is how they fought hammer and tongs to prevent the establishment of non-denominational schools in case their fucking power would be undermined.
Very well, Bishops, old chaps. Since you say you own private schools, pay the private fucking water charges and shut the fuck up.
It’s not as though you don’t have the money: maybe you could use the billion-and-a-half euros we gave you to cover your costs for abusing all those children?
