What community is that then?
Antitheist, atheist and skeptic groups he has been associated with including the BHA and NSS...although I'm not sure whether the latter two have disassociated themselves from him although Krauss is no longer on the list of honorary Associates of the NSS.
Krauss was a leading celebrated proponent of the old religion makes good people bad business and even declared that science made people good.
Such zeal as the American Humanist associations have pointed out has led, according to them, to atheists overlooking behaviour in order to support zeal.
Are you of the opinion that the circles he has moved in should take him back into their bosom?
