Preachers want to impress on you how awful things are so they can sell you their religion. We liken it to breaking your leg to sell you a crutch.
Do you think Europe has descended into chaos? There are higher rates of atheism there.
How does straying away from religion make thing better? Easy. Religion is a broken model of the world. Having the correct model of the world enables a society to make better policy decisions and individuals to make better choices.
Take a look at this article: (http://moses.creighton.edu/JRS/2005/2005-11.html). It shows how religious belief in various nations is correlated with a number of social ills, including abortion, teen pregnancy, lower longevity, infant mortality, etc. How can anyone claim that religious belief is good for a society with evidence like this?
