Welcome to Atheist Nexus with its 8000 good friends.
A group you may like is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion..... ) with its 120 discussions and numerous video films.
One discussion (over 65 posts) is "Proud to be Atheist".
There's much to feel good about
because atheists and humanists hold the intellectual and moral high ground that is far removed from the pathetic superstitious god believers who are slaves to an unthinking controlling clergy and their imaginary beings.
