The promotion of critical thinking/morality/philosophy courses as mandatory, two semester high school classes is another good start.

In fact... I'd say things like the laws of logic, logical fallacies, syllogisms, tautologies, epistemology, and the veil of ignorance should all be taught as early as 8th grade, if not 7th.

Additionally, comparative religious courses should be much more prevalent, perhaps as part of the aforementioned curriculum, in a way that openly examines the morality of religions, so that people can no longer simply ignore the atrocities and gross immorality displayed by the gods of the major world religions, in favor of the warm fuzzy shit that makes them feel good.

To be clear, by the promotion of atheism, I mean the promotion of the notion that there is no good evidence for the existence of any god. That's it. There are no tenets. it's not a religion, despite the "ism" attached, and that important distinction should also be promoted, as it is a response to a claim, not the claim itself.

Further, removing the tax exempt status from churches, or, at a minimum, changing those laws to require that religious organizations open their books and give a full accounting of their spending, would be a big step in the right direction.

Also, for religious organizations that seek to also provide charitable services, there should be laws in place that strictly and explicitly prohibit any form of proselytization at any stage of the process, from collecting donations, to delivering the goods or services, to leaving. No flyers, no songs, no invitations to church, none of it. Whatever they give, they give without even the implied obligation to partake in any sort of religious ritual, media, or discussion.

Same goes for establishing better secular sobriety networks, removing court ordered mandates to religious organizations such as AA.

Despite a strong persecution complex, Christians and Christianity has a foothold in fucking everything from addiction to charity to politics.

Take away that preferred status and level the playing field with other non profits, OR afford the same rules to secular charity and aid organizations and my guess is we'd begin to see the playing field level a bit as far as the ability of those organizations to grow.

The promotion of secular humanism is another key to the puzzle, and one of the most critical. We have to dispel entirely this notion that any of our value or morality is derived from any religion, let alone any deity, which means abolishing the concept of original sin.

This also goes hand in hand with stepping up our game in the mental health arena. People who are bred to believe they are inherently evil and can do no good absent the presence of some higher power is a net negative, particularly in Christianity, as it is a gaslighting manipulation that sells you on two things:

The idea that you're sick, and the idea that Christianity is the cure.

To that end, I'd argue that protection from Christianity starts with seriously limiting the ability of christianity- and christians- to prey on the poor, sick, compromised, incapable, insecure, or otherwise vulnerable, in addition to leveling overt challenges to the entire framework of the religion from it's theology to it's infastructure, to it's political reacg

There's a lot that can be done, but pushing back against this shit with education, logic, reason, promotion of science and the scientific method, understanding standards of evidence, understanding the apologetics used to convince people that a god is real (spoiler alert: it's nearly always a logical fallacy), better education on evolution, particularly how it pertains to biology, etc...

For any atheists and/or those who are questioning, or have already deconverted who are interested, or know those who may be, there are resources out there:
