Where do Atheists Get Their Morality?

I would like to suggest an alterantive answer to the question, "Where do atheists get their morality?" than the standard attempt to defend some moral theory.

The answer that I would like to propose is:

"A lot of theists want to know where atheists get their morality because theists are bigots looking for an excuse to hate their atheist neighbors, and 'You are morally inferior to us' has long been a favorite dehumanization technique of the hateful bigot. Clearly, atheists do quite well when it comes to behaving morally, at least as well as their Christian counterparts. It may be natural to express some curiosity as to why this is the case. But to cast atheists as morally inferior in order to generate a reason to hate them - that's not a course that a truly moral person would ever pursue."
