Welcome to Atheist Nexus with its thousands of good friends.
Join groups when you can, like the busy discussion group “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion..... ) with its 120 discussions and numerous video films.
One discussion (over 65 posts) is called "Proud to be Atheist". There's much to be proud about because atheists and humanists hold the intellectual high ground, way above the superstitious god believers held in mental slavery to their imaginary beings.
This is not being fanatical. It is being realistic in having something to be proud about, and not reserved about.
