Why we need Atheism+

Adam Lee makes a good point in Diversity Doesn't Just Happen: A Response to Michael Shermer

... diversity isn't an optional extra (as Shermer implied when he said it's possible that women and minorities just aren't interested in skepticism, and we shouldn't worry about that). If we do nothing, then the skeptical movement will end up like the Republican party: a shrinking remnant of white men in an increasingly diverse, majority-minority society. [emphasis mine]
