The Brights movement is a social movement that aims to promote public understanding and acknowledgment of the naturalistic world view. It was co-founded by Paul Geisert and Mynga Futrell in 2003. By definition a Bright is person having a natuarlistic worldview or whose worldview does not consist of supernatural elements. Bright is supposed to be a positive term unlike the word atheist. Homosexual is not as a cheerful term as gay. Words like infidel, heathen etc are insults. Philosopher Daniel Dennett has argued that if religious people find the term Bright offensive they must invent a positive term like super, people whose worldview consists of supernaturals.
Brights strongly encourage one another to interact with people of different worldviews, whether they are theists, supers, or brights. They believe that neither is to be socially denigrated or personally disadvantaged simply for being persons whose worldviews are differently grounded. (Conduct is another matter - that which violates secular law, for example). The ideal is a fair foundation for all citizens, whatever their worldviews may be. The noun Bright is spelled with the B capital unlike the adjective bright. Calling atheists Bright doesn't make one bright. (Bright here means intelligent) Despite this intelligent people are more likely to recognise that religion doesn't make sense) Similarly being a homosexual does not make one gay (happy).
