Why am I concerned? I'm concerned because it's growth in
  popularity. With popularity comes power. With power comes
  responsibility over people. With responsibility over people
  comes humanistic values or absolutist values or some mix
  inbetween. Absolutism can be very dangerous. It's not today's
  Internet atheists I worry about. It is the grandchildren of
  today's Internet atheists. It is Generation Z and the one coming
  to an Internet that finds it ok to mock other human beings. This
  isn't the Internet I started with. This isn't the humanistic
  values I grew up with. These will be the people that will
  eventually be in power and they are and will grow up on the
  Internet they are receiving and its value systems expressed by
  the people on it. This is why it's important to me. Past the age
  of 7, parental influence is minimal. It's peers after that.
  Peers include virtual peers like TV and the Internet and all of
  the people they encounter on it and all of the Memes they see.
  This is why I am concerned. Today's ways will die out. People
  are being raised on the Internet TODAY. Some of those people
  will be in power later and make decisions. What kind of value
  system will they hold when they do so? Humanistic values?
  Nihlistic values? Absolutist values? This is why I'm concerned.
    == Also, notice what I wrote: It has little to do with atheism
  at all. I know plenty of non-atheists who are just like that.
  I'm not even defending Christians per se. I'm talking about the
  tendency to people to automatically believe things about groups
  they don't like. That's a bad thing. It's a bad thing.
