Unfortunately it's a case of preaching to the choir since the arrogant tone of the article will turn off anyone who is attached to an organized religion. It seems to be better suited for non-religious people who want to pat themselves on the back for being 'smarter' than the common man.
The statement about "blessed are the poor, hungry, etc." being used to encourage people to donate money might be true now, but it overlooks the original purpose of the statement, made before there was a central Church to donate to. This aspect of Jesus' message was a poverty gospel. In other words, the message was intended to make poor people feel better about their lot in life.
This is still an important purpose of religion; it's not simply that well-to-do people are too well-educated to believe in religion, it's that people who are disadvantaged feel like they need a friend in a high place just in order to get through life. So it's all well and good to say that people should know better than to believe in God, but I don't see how it helps those who are needy and don't know where else to turn.
