atheism, philosophy and emotional immaturity

[Angrboda]

Beliefs or non-beliefs only require justification when they affect you directly.

What is the justification for morals? What is the justification for free-will? What is the justification for justice? Human rights? Perpetual identity? There is none. Yet these effect us the most.

The most sacred of humanity's beliefs are without justification. They cannot be proven but humanity needs to hold on to them.

I'd like to see you justify that humanity "needs to hold onto" free will, "justice" (whatever you mean by this), perpetual identity (really?), and human rights (as normally conceived as objective truths independent of arbitrary political establishment of them), please. I don't see any of these as "necessary" to humanity.

(Of these, only justice seems in any sense useful or necessary, but the fact is, justice is as often honored in the breach as not, and humanity appears to be managing quite fine, regardless. Additionally, justice of a sort can be justified.)
