It's funny to see Uncle Bob take offense at being called a fundamentalist and then follow with this gem:

> If you aren't doing TDD, or something as effective as TDD, then you should feel bad.

"Fundamentalist" is hyperbole, which is par for the course in blog posts that want to attract traffic, but the sentiment is real, and Uncle Bob perfectly demonstrates that the qualification is justified. Like most extreme advocates, he's trying to get us to believe in something based on faith instead of facts.

"If you don't do it, you should feel bad".

Last time I heard that was in a church.
