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 a narrow-minded controlling clergy and their imaginary beings.
There's a huge group of Dallas/Plano Atheists that has meetups every week - maybe more often than that. They're an active, friendly bunch. The Frisco group is much smaller and only meets twice per month with (hopefully) special events thrown in from time to time.
Howdy neighbor - welcome to the Nexus - to Frisco Atheists and Tx Heathens. I think you'll like it here. There's tons of great people (that definitely includes the first person to post a greeting on your wall!)
