This is... a ridiculously oversimplified caricature of atheistic philosophy, presumably now posted (as the original post predates the current controversy[0]) to imply the obviously incorrect syllogism that if we accept people who are privately religious we're somehow obligated to not only accept outspoken racists, but put them on a stage.

[0] The idea that it should be controversial to deny a platform to someone who's chosen to become a public figure by promoting racist violence is absurd, regardless of any technical accomplishments (which would be a pretty strong characterization of the pointless Turing trap that is urbit). I've already canceled my flight for LambdaConf and in the future I will happily decline to work with people who failed to do so.
