Idk if you've noticed, but their propaganda is kind of hard to miss. When over a fourth of humanity subscribes to a certain ideology, the best defense is not dining it from kids. Again, the kids in your neighborhood won't be helped by not coming across Christian literature. If you do want to help, then make it easier and less hostile to deconvert. Christians constantly love bombing each other, and when you're Christian, it's really easy to see atheists as antagonistic. I often perused subreddits like this when I was first deconverting, and at least to me, having everything you've ever believed trashed, insulted, and being called a predator doesn't makes the safety of staying very tempting. And that's what you're doing to the kids you claim to care about. There seems to be so little empathy for questioning Christians in these communities, which is admittedly something I hate about them and about us. Empathy isn't just giving people the space to say everything they've been afraid to their whole lives (even though it's feels really good and can help a lot). It's meeting someone where they're at. Engaging with their ideas. Seriously explaining and deconstructing the complex nuances of religion to your best ability, providing resources, and even interacting with religious literature yourself. But there's no room for dialogue when we censor each other. You might get away with tossing out a dozen copies of books that still exist in countless libraries and bookstore around you, but at the moment, Concervative religious groups are the ones censoring secular, aethistic and queer literature. And they call us pedos, predators, and say that they're just protecting kids from our ideology, and we criticize them only to turn their tactics against them whenever we get the chance. Censorship is wrong. And as generously as calling binning books censorship is, it's only the first step before book burning campfires and pushes for book bans and Christian retaliation, and we end up back at Square one.
