Both of you are right, and it illustrates the problem with "freedom of religion" when applied to fundamentalism. On the surface, it seems like it's giving everyone the right to choose their belief system, but in reality it just means the government isn't allowed to tell you what to believe. All other entities are free to use whatever dirty tactics they choose. For most people who grow up in a religious cult like radical Islam or the FLDS or IBLP, freedom of religion is only a theoretical legal right, not a reality.
We aren't all created equal. The law treats us all as if we were, which is necessary for a functioning democracy, but the reality is that some people simply can't and won't ever exercise their freedoms. They're too afraid, or too compliant, or too neurotic, or too stupid, or too complicit. They pass the belief from generation to generation because that is the ultimate and final aim of the belief itself. All other functions of the belief system are slaves to the end goal of making more Muslims/Mormons/Quiverfulls, who will then make more Muslims/Mormons/Quiverfulls.
I'm not a Redditor, so I don't think this means we need "freedom from religion" instead. Religion itself is not the problem; fundamentalism is. It barely qualifies as faith or spirituality in any meaningful sense. It's an unevolved and cancerous form of tribalism which weaponizes the human capacity for spiritual meaning and deep faith as a means to perpetuate itself at any cost.
I don't think the solution is for the government to regulate which religions are considered fundamentalist and ban them for infringing on people's freedoms. To be honest, I have no idea what the solution is. I'm not naive enough to think everyone can escape. Some people are just cattle and will forever be led around by some sort of extreme ideology, hence the rise of modern forms of fundamentalism without the God part. It's almost like they crave being told what to think, say, and do because they hate having to choose for themselves. The only way I've found to deal with these people is not to let them into my life. As a society, we have to be especially careful with letting them into positions of power, unless we want our nations to be completely captured by them.
