I just read a quote on a blog that said 'there are two types of people in the world - one with brains and no religion and one with religion and no brains.' (apparently taken from an 11th century text)
Obviously I disagree with that, some of the most intelligent people i have ever met with are committed Christians. Interesting how those who seek to dismiss religious faith have to make themselves feel better by saying those with faith are stupid. Not that i deny that religion doesn't make people do stupid things! Or rather that some people who profess religious faith do stupid/abusive/careless acts - but we could say exactly the same about atheists or agnostics or whatever.
My experience has been that in the end, those who disagree with faith end up shouting at the 'faithful' - there are some things that arguing doesn't achieve. No one has been argued into the love of God!
