If this preacher is so convinced that Islam is evil why doesn't he just preach that to his congregation? Because preaching ain't gonna get him noticed! There are plenty out there preaching that Islam, Christianity, Judaism etc is evil but it's not big news.
I haven't got a problem with someone burning the Quran or indeed any 'holy' book. If you think that's a clever thing to do then go ahead, it doesn't alter my view of religion one iota. But if you're going to do it just do it! Don't be running to the media telling them you're going to do it. The bloke's an effing attention seeker and having a 'flock' of around 12 people (which seems to be the total of his congregation from what I have seen), just ain't enough attention!
