We need people to accept that there is no "personal" god. That is, one that you can call upon to fix the things in your life, or one that routinely enters into conversations with lots of people.

The problem is that it is too easy for people to claim conversations and divine guidance. The sick or untruthful benefit from this. In that way, they can direct others to do things that are inappropriate. They can claim an authority above and beyond their own; one that they do not have.

Often people just need a reason, so it best not to make it easier for them to get one.
