If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
While there are many people who are annoyed by Christian Evangelicals, I feel that it is difficult to argue against their effectiveness. They exist because they are willing to talk to people again and again about their beliefs until those people convert.
Do you have any reason to believe that Christian Evangelicals are ineffective at persuading people? Keep in mind that a 5% conversion rate is doing a pretty damn good job when it comes to changing people's minds.
