No, the joke is the association of these virtues with religious people. The bold text just makes it seem like one of those pamphlets that crazy people hand you in the bus.
In a fairly long life, it is my experience that religion makes people less humble and less kind.
I would point out, for example, that crime of all types are significantly higher in counties with a highly religious population like the United States or South America, and significantly lower in more atheist countries.
We need look no further than the United States, the country with more Christians in it than any other. America’s long, unbroken record of invading other countries which never offered it any harm, setting them back generations and killing swaths of their inhabitants, should show how a “Christian” country actually deals with the world.
American routinely die of exposure in the street due to lack of money. Americans routinely die of diseases that are easily treatable in other countries. Both have happened to friends of mine before, and it will probably happen again, as I have at least two friends who are homeless at this time. This doesn’t happen in atheistic countries, because they take care of their own people in a way America never would, which is why I left America after thirty years and am writing this from the godless Netherlands.
Moral and ethical decency have nothing to do with delusional beliefs in non-existent Gods. It’s funny that you quote “Muslims, Christians and Jews” approvingly, because since these religions disagree on so many matters, at least two out of three of them have to be entirely wrong about how the world is put together!
