All atheists are presumably humanists Since what else could they be?
Humanists do not agree with with rebirth even though the evidence is strong; one may search this thread for 'Eisenbeiss'.
all atheists are not humanists ,some are selfish , rotten, cruel, derranged and destructive as are many believers in a God.
There are many sub sections on belief and generalisations placing all non believers in the atheism "box" is too simplistic.
Many non believers, non Christians , non practising Christians and Christians in name by default due to their parents or community are actually practising large elements of this lifestyle in this day and age.
Apathetic agnosticism
Apathetic agnosticism claims that no amount of debate can prove or disprove the existence of one or more deities, and if one or more deities exist, they do not appear to be concerned about the fate of humans. Therefore, their existence ( or absence of it) has little to no impact on personal human affairs and should be of little theological interest.[6]
To further the debate on the theory that religion is a comfort for the poor and the disempowered here are some links. I would suggest that the weight of evidence suggests that mainstream religions and believing in God has a positive influence in many/most of the poorest Nations and communities. Radicalisation and fanatisism has the opposite and severely negative effect
