Theism is the first, and oldest problem. We have freed ourselves from it, yes, but that does not mean we have solved it. There are still churches.

Indeed. When a community contains more than a critical number of theists, their irrational decision making can harm themselves and the whole community. By deconverting theists, we help them and everyone else.

I'd like to see a discussion on the best ways to deconvert theists.
