More than ever, America’s atheists are linking up and speaking out — even here in South Carolina, home to Bob Jones University, blue laws and a legislature that last year unanimously approved a Christian license plate embossed with a cross, a stained glass window and the words “I Believe” (a move blocked by a judge and now headed for trial).

They are connecting on the Internet, holding meet-ups in bars, advertising on billboards and buses, volunteering at food pantries and picking up roadside trash, earning atheist groups recognition on adopt-a-highway signs.

They liken their strategy to that of the gay-rights movement, which lifted off when closeted members of a scorned minority decided to go public.
