One or two of us would probably be happy to see religion just fucking go away, but it appears that we are saddled with it. Much of the time, it is not a problem, but also much of the time it is, especially when the person on the dais goes to whipping the followers into a froth.
Many of us favor imposing taxes on religious institutions, because we have the massive orgs that abuse the privileges granted them in ridiculous ways that appear to be way beyond what a reasonable person would consider reasonable. On the other hand, there do appear to be small-scale operations that show some indication that they are doing genuine good in the community, perhaps enough to justify their privilege, and may not deserve the impositions that the big orgs probably do. These smaller operations, I believe, originally served as the heart of their small towns, which was the justification for protecting and preserving them.
Thus, the question is, by what metric would we decide which law-abiding religious organizations are worthy of privilege (such as tax exemption) and which are not. I believe I know.
Religious belief is about you and how you relate to the unknowable. It is not about that other person or how they relate to the unknowable, or to you. As long as the message remains personal, about your spirituality, even if the content is unalloyed bullshit, it can be tolerated, but once it goes off from you, it stops being tolerable.
There are constraints on our other constitutional freedoms – religion needs them too.
