I think Richard Dawkins hit the nail on the head, so to say, when he said that people should be left alone to practice their religion, but the thing about it is they don’t leave the rest of us alone.
On those lines alone, I think Dawkins has my vote. (Vote for what, I’m not sure, but he has it.) It’s not religion in itself that is annoying and troublesome; it is what people do in the name of religion.
So if you ever wonder why people have a problem with religion – perhaps your religion? – take a look at what people do in the name of their religions.
