Heya, hideousmonster! I read your testimonial and just wanted to say that I find your process respectable.
I'm an agnostic atheist myself and while I might disagree with various points you might make, that's not what I'm here to comment on. Your testimonial evidences a great deal of thought. Changing views, sampled perspectives; gives the impression that you're thinking, and not merly thinking, but thinking from as informed a basis as you can manage.
None of us can claim (truthfully) a truly informed basis about what does or doesn't exist beyond whatever we convince ourselves is plausible or implausible as determined by whatever evidence we attribute the winning value to, and I respect thinking about it more than I ever will anybody's absolute claims one way or the other.
So, kudos for that. You're not pretending to know things you don't. for what it's worth, which may be absolutely squat...I approve of this testimonial!
