As someone who is religious, I think this is a bad approach because it is transactional and tries to force the will of someone unfortunate. Both of those directly oppose the values of my Christian faith (grace and freewill).

But unlike others, I don't agree that religious charities should not do any proselytizing. A genuine religious person believes their doctrine, not just in being a good person like anyone can be. Christians believe there are eternal issues at stake.

The point is that basic services should not be conditional and proselytizing should invitational, not mandatory.
