Its like people who preach abstinence and nofap only. In theory its the type of aspirational ideal to strive for. In reality it drives most people insane and they will break down one way or another soon enough. There is a balance to be found and trying to take the opposite extreme will drive most people to madness, and this applies to most things.

One of those wacky Christian ideals is the idea that sin is inevitable and human, as long as you are working on it and recognizing when you fail you are still good.
