Good and Evil

So a couple of days back I read this blog post about an elderly mormon couple that travels around the world forcing their beliefs on people around the world. That didn’t bother me, really, until I read that they “aren’t hoping to change the world, but they are hoping to make it a bit better by introducing people to Christ” or something like that (I don’t remember how exactly they phrased it). Now THIS bothers me. Even though I am Christian, I don’t understand how a person can make the world a bit better by forcing their beliefs on others. What, all the people who profess other religions are simply not able to make a difference? Is it a privilege of those who believe in Christ?
