300 years, yet atheism has not grown into a viable movement | Bart Campolo

[Astreja]

What you're espousing is secularism i.e. separation of church and state, etc. That's great but it doesn't address some problems such as:

1 - Some people (especially young people) want a more defined identity and ethos, than is provided by chaotic individualism...

But why does that identity and ethos have to be centred on belief in particular?  (Disclaimer:  I am a member of a local humanist group, and do identify as a humanist.)  For instance, I find much more of My identity is connected to music, which is also where I get a sense of community.
