Most of it’s really good and gets it right.
On one level, this is just the logical culmination of the huge upsurge in interest prompted by the so-called "New Atheists" and the growth over the last few years of a recognisable community or movement based around ideas of atheism, scientific scepticism and a progressive political agenda. While atheism is, by definition, no more or less than a non-belief in God, in practice it clusters with a variety of other positions, from pro-choice to campaigns against homeopathy. People who espouse "liberal atheism" as it might be called, oppose religion for political as well as philosophical reasons, just as the forces of religion seem to line up – though of course not exclusively – behind seemingly unconnected issues such as opposition to abortion and same-sex marriage and, in the US, gun-control.
Atheism+ is, at its most basic, an attempt wrap things together more formally, to create a movement that prioritises issues of equality and does so from an explicitly non-religious perspective. Some would say that such a philosophy already exists in the form of humanism. Others prefer the label Skeptic. Atheism+, however, seeks to capitalise on the sense of identity that has grown up around the word "atheism" during the past few years. One supporter of the idea, Greta Christina, celebrates the term as "a slap in the face that wakes people up."
The only problem? The figure caption.
Atheism+ is a reaction against the “New Atheism” of Richard Dawkins.
Nope. The body text had it right: it’s “the logical culmination”, not an opposition to the New Atheism. I’m actually doing a talk on just that next week in Denver — as the New Atheism was the incorporation of science into atheism, Atheism+ is a synthesis of social justice into the New Atheism.
