I haven't heard about this discussion for a long time, I think it has died, or at least died down.
I do not see who you can prevent anyone from leaving a faith?
Ok. I was not familiar with the problem because in DK churches are upheld by the state (while being largely ignored by the people who pay for them.)In the US, at least, all religious organizations are tax-free. Even those businesses and properties they own which are not strictly connected to religious activity are still exempt from taxation.
I actually have no idea how it is here in UK.
