With religious leaders pushing for amnesty and high immigration and welfare for immigrants and illegal aliens, all based on their perception of Bible-based charity, I thought this story from Davy Crocket was a good explanation of the dangers of going down that path.
Radicals from the left say this story is not true but why wouldn't they.
A little long but I think well worth it.
