I can speak only for my own Church. The Catholic Church - and we do more charitable work, provide more money, provide more aid, food, shelter, clothing, etc than any other organization on this earth.
And own a tonne of property, don't allow priests or nuns to shag, are against abortion, and don't believe in contraception in an already over crowded world...and I would argue the Red Cross do more....
There are up and down sides....
You can argue it if you want. But the facts will not support your opinion. You are trying to compare an apple to an orange anyway, so it's irrelevant. The fact remains that the Catholic Church is the largest charitable organization on the planet. It does more, gives more, feeds more, houses more, supports more, and does more for humanity generally than any nation, charity, group or individual anywhere.
Your comments about 'shagging' are not only irrelevant, they are petty, childish and stupid so I'll ignore it.
Also, simple fact: if we force churches to pay taxes, they will have far less money to help those who need help. You might think that's a good idea but.... if they pull their support then the government will have to take up that slack. Logic. And who the **** is gonna pay for that? Yep, taxes.
