"Protestant robot". If you ever run into those stone-faced evangelical Christians who immediately start talking to you about Jesus and being saved, and answer everything -- and I mean everything -- with another Bible quote, in a monotone, you'll know what I'm talking about. Granted, not all evangelical Christians are like this, but a large enough minority is that it makes a mockery of Christianity to other decent people.

Simply put, one of those things that brings Catholics and atheists together.
