What are Muslims' views on this article explaining Iran's persecution of Christians?

I'm glad that they didn't stone these people for being apostates. At least they're not following their holy book word for word. Why can't everybody in the world just allow people to have whatever crazy beliefs they want without being subjected to violence? An intelligent person would know the only genuine way to win over believers is to show that their beliefs are better. This is just gonna cause more hatred and violence.
