Faith is a measure of irrationality

[Mr Greene]

You've heard people say it before, "I have faith" or so and so has a lot of faith. What does that mean really? What is having a lot of faith?

...
I remember being in a restuarant and a man came in and said he was a man of faith. He had an incredible sense of superiority. It's sad that a bold statement like that can be said with such gusto in 2014.

I think faith is directly proportional to irrationality.

In my experience the statement tends to say more about the person making it than the subject, for example; I've been described as being "very christian, I must have a lot of faith..." on numerous occasions. This always results in a rather awkward silence as I resist the urge to laugh. However the people who make this type of statement are invariably the more religious types who talk first, think later (if ever) they're also the usual suspects when someone is out to twist the system to their own ends.
