Dear Christian, ... p.s. your God is obsessed with foreskins, you lose either way.

FWIW... The obsession with foreskins is more of a USAian thing from some corn flake capitalist. I think christians outside USA are generally uncut. It's a national thing, not a religious thing.

Christianity legalized the foreskin almost immediately. It's still legal today. TBH I don't think christianity would have grown so popular otherwise.

... Then some of the believers who belonged to the party of the Pharisees stood up and said, “The Gentiles must be circumcised and required to keep the law of Moses.” The apostles and elders met to consider this question. After much discussion, Peter got up and addressed them: “Brothers, you know that some time ago God made a choice among you that the Gentiles might hear from my lips the message of the gospel and believe. God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us. He did not discriminate between us and them, for he purified their hearts by faith. Now then, why do you try to test God by putting on the necks of Gentiles a yoke that neither we nor our ancestors have been able to bear? No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are... It is my judgment, therefore, that we should not make it difficult for the Gentiles who are turning to God..." - Acts 15

What if, after you die, you find out you’re dead, and you’ve wasted your precious time all along?

I mean, what does it mean to "waste time" in this context? There's a certain existential dread that comes with the mystery of death - really the mystery of consciousness generally speaking - and we all cope with it as best we can. I don't think a ritualized means of managing one's anxiety is time wasted. If your genuflections to a carving of a guy on a crucifix sooth your own anxieties of loss-of-self, more power to you.

But it does feel a bit like someone asking "What if you stepped on a crack and then it really did break your mother's back?" I mean, that would be very scary and sad. I can't see the correlation between these two things. I'm not going to painstakingly tip-toe down the sidewalk out of a concern I don't take seriously.
