That is why it's a worthless belief to anyone capable of rational thought.
The concept of having to answer to a higher source is what angers most Secular Humanists. Gee, just imagine what the Afterlife will be like when someone conducts an audit of all your past experiences no matter how trivial.
I also note that Secular Humanists are among the most arrogant people I have ever encountered.
Secular humanism does not, in any way, suggest that life is totally meaningless. The no divine purpose, absolutely.
I have never met a secular humanist angry at the notion of answering to a higher power. Typically because the whole concept of a higher power is anathema to them. Why would they be angry at something they don’t believe in?
I, an admitted agnostic, would not cringe at the idea of such an audit as you suggest. I am not perfect, but I don’t shrink from my actions, as I have tried, and continue to try, to live by that very simple, golden, rule. I am no more or less a sinner than you are (as Christians believe we are all sinners, right?), should I be proven wrong and stand before the pearly gates.
Arrogance comes in all shapes and sizes. You exhibit plenty, given your second paragraph (anyone capable of rational thought - as though you have a monopoly on rational thought).
I figure that it’s a great big world out there, and I’m OK with the idea that we can believe different things. I have no need to proselytize you to my way of thinking, and frankly, I would not be terribly open to your proselytizing, either.
