One of the last nails in the coffin for me before I went 100% atheist was when I was at a Jewish “youth group” religious gathering where they brainwash kids. They were trying to tell us earth and the universe etc is ~5000 years old. I was old enough to know that is absurd but naive enough to not know there’s a lot of evil or delusional people out there that would lie to you about such things. I was so frustrated and confused, almost to the point of tears. Looking back, that was a major loss of innocence for me. Ever since then I view any religious nutjob with suspicion and fear tbh because they are unhinged and willing to believe anything without a shred of evidence; indeed they hold their beliefs despite overwhelming evidence to the contrary. Terrifying. Bunch of plague rats, the lot of them.
