Are atheists given a guardian angel?

An interesting question that occurred to me as I was studying angels was this: if a person is an atheist, will that person still be given a personal angel?

The authors of The New Theological Movement addressed this issue. And while the answer they gave was to another question, I think it would also answer mine.  They wrote:

Will the anti-Christ have an angel guardian? If he is a human being, he will have an angel guardian. Even though he will be a great enemy of God, the Lord will still love him – the expression of this love is the gift of a guardian angel.

I imagine that answers my question.
