FYI, denoting the word "Christian" as a default label for a good person, even if it's meant as a complement to a non-christian, essentially reproduces cultural assumptions of christian supremacy.
So saying a christian is behaving like an atheist when they turn away from others in need and saying an atheist is behaving like a christian when they help others in need is not great.
Would you say this about a person who is Muslim or Jewish? They'd be annoyed for very good reasons.
