Welcome to Atheist Nexus with its 8000 good friends.
A useful group is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion....) with its 125 discussions and numerous video films.
One discussion (over 70 posts) is "Proud to be Atheist".

because atheists, agnostics and humanists hold the intellectual and moral high ground—far removed from the superstitious god believers with their imaginary heaven and hell. Yes, christianity is a death cult---and potentially very bad for children who are conditioned into accepting irrational beliefs.
