Jesus said to look at the fruit to judge the tree.
Christianity has had its problems, but in the modern world, no other idea inspires more charity than Christianity.
In my town, Catholic Charities feeds hundreds of homeless every night, and gives them a warm place to sleep when it is cold.
I don't see atheism inspiring that kind of selfless dedication to others.
On the contrary, the fruits of atheism seem to be unhappiness, intolerance, and hate.
Look at the way this forum's atheists behave, or any other forum's atheists.
Look at the lawsuits they are constantly launching against Christians.
Look at the way atheists have behaved when they controlled countries like Russia, China or Cuba.
Or look at the terrors of the French Revolution.
I agree. I'm an agnostic but I see the good works that these people do and I support them.
