This is another of the sessions from FtBCon3. Lyz Liddell of the Secular Student Alliance gives a great primer here on privilege, and she does it in a context that movement atheists should generally be able to understand. The talk is titled, “Identifying and Addressing Christian Privilege in Intersectional Spaces”.
I think it’s not a coincidence that just a couple months later, the SSA announced it was working to address privilege more generally. If you’d like more information on where their focus will be and how they mean to get there, I interviewed August Brunsman on Atheists Talk on that topic a few weeks ago.
