Loking at both photos and their website, I have no idea what they are on about. It seems to me that they are making themselves judge, jury and executioner on all issues.
Whatever it is they are teaching it certainly contradicts everything Jesus has taught. I'm certainly not impressed by people like this church (and I use church in a very loose way).
These people don't represent Christianity in any way in much the same way the men responsible for the Bali bombings don't represent Islam.
