Hello Andrew Welcome to this friendly Internet community of rationality and peace, common sense and freethinking evidence-based wisdom.
We invite you to visit and join the busy group "ORIGINS: Universe, Astronomy, Life, Earth, Humans, Religion, Gods, Atheism, Evolution, Darwin..." with 1100 discussion topics and 4180 members. http://www.atheistnexus.org/group/originsuniverselifehumankindanddarwin There are over 1100 groups in Atheist Nexus. Do go visiting and try "Hang with Friends". Terry
There are LOTS of groups and forums to explore here. I particularly recommend the active, relaxed, freewheeling Hang With Friends. Texas Heathens is worth a look too; and Writing to Congress offers inspiration on ways to respond to our "unpresidented" political landscape.
Groups don't clutter up a "timeline" or "news feed" page; some of us are members of many dozens.
And I keep discovering things through the "Latest Activity" in the lower right of each page. (Mobile view: menu, Activity.)
