You've completely not understood raikiri's post at all haven't you.
No one is advertising a religion here. It's a religious charity. And their slogan is "praise God". If you're a muslim and you want to assume that's referring to the Islamic idea of god that's you're choice. It doesn't say "become Muslim" or anything whatsoever to that effect and if you honestly do feel enticed to become muslim after merely seeing the words "praise God" I really do feel sorry for you.
Personally I'm not bound to any religion so when someone talks about god it's simply God alone not tied to any man made religion. And if someone wants to praise whatever they think God is then good for them but that's another story because God is evidently evil.
I love how people automatically get up in arms at the first sign of anything remotely muslamic though.
