Every person is religious

[Ahriman]

No one cares, least of all me, still not religious though!
In what way am I "clinging to some kind of post-life existence" ??  I'm just pointing out that after I die I will no longer exist exept in the memory of those who knew me.  That memory will have nothing to do with me though and will not affect my rotting body at all

You clearly still think you matter. You don't. The sooner you can realize that, the better off you'll be.
