Just to understand here: you're claiming that since atheists have fewer children, they'll eventually be out-bred by the religious?
Atheism is, in general, a consequence of, not a cause of, all the things that also result in lower birth rates. Birth rates in the US started to fall a lot earlier than religiosity did.
I'm saying that atheism and lower birth rates are caused by increases in overall quality of life.
I'm not addressing whether or not atheists in fact have fewer children. That seems self-evident. I'm saying that you're misidentifying cause and effect here.
I will say that its a little weird to suggest that atheism will die out simply because atheists will have fewer children. Atheism is not, in general, spread via proselytizing or family or community education (religious apathy, certainly, is spread that way but not motivated self-identification as an atheist), so much as what you might call "anti-religious experiences": experiences that set a person to seriously questioning then rejecting the concept of god(s). For good or ill, modern scientific knowledge has made religious experiences (that is, powerful emotional experiences that so defy explanation that a person feels compelled to accept them as the work of god(s)) much rarer.
So you're saying that atheists have a vastly higher quality of life and that explains the fertilty gap? This is just a bare assertion, and absurd considering all data about well-being and having children.
Atheism won't die out, but atheists largely will. The atheists of the future will have had religious parents. In this way, atheism is a persistent freerider, gluing itself to the coattails of belief.
If you're not going to respond to my posts in good faith, then don't respond.
From the fucking top:
PEOPLE are experiencing greater quality of life than ever before. This has led to several things, including lower birth rate and lower religiosity.
