Atheists, tell me, a Roman Catholic: why should I become an atheist?

[brewer]

Balaco, why is your god referred to as a "HE/HIS/FATHER"? Why does your god have a sex?

"Die for a lie" is a nonsense argument. Consider a religious war. At least one side is wrong but prepared to die for it.

But then lying and being wrong aren't the same thing anyway. Just because you believe something is true, it doesn't mean it is. There are also plenty of reasons why someone might die for something they know to be false anyway. It's appealing to motivations rather than facts, which is unreliable.

Exactly. A lie honestly believed is still a lie, and will never become truth no matter how earnestly it's believed or by how many people. In fact, the more belief, the more faith, the greater the number, is required to prop it up, the more likely it is actually to be a lie. It's what you do once you realise that it's a lie that determines your character as a person.

I had a similar experience with a similar outcome.  I finally came to the conclusion that the idea of an all-loving god who loved me more than I was even capable of loving would not lay down one right path, allow Satan to lay down tens/hundreds of thousands and then simply expect me to find the one right path on my own with the intention of lighting me on fire for all eternity if I were tricked into choosing wrong, as the Bible clearly says most people searching will be, was a massively idiotic idea.

I was taught that God doesn't give us undeniable proof of his existence as a test of faith...those with righteous minds would find him. Joker and any other Catholics, what are your thoughts on this?

That is not backed by the Bible, though.  When Thomas, who walked with Jesus, saw his miracles, heard him say that he was coming back in three days and then looked upon his face STILL did not believe Jesus didn't quote any bullshit about not giving him undeniable proof as a test of his faith.  He gave him undeniable proof.  The idea that the same God who had Moses have a spell fight with Pharaoh's wizard, destroyed Jews, Cities and the entire world, took a man into Heaven bodily in a fiery chariot, healed the sick, turned water into wine, walked on water and raised the dead somehow became a mysterious goth kid who sits in the corner just letting you wonder about his power is ludicrous.  This claim simply does not match the many descriptions of how God operates found in the Bible.  It is purely a modern creation designed to explain away the current absence of magical working rather than confront the reality that miracles as described in the Bible simply don't happen, so they probably never happened.
