Did you read the article?
It was the school board which decided that Christian groups could come into the school and give out Bibles to the students. It was only in response to that program that the Atheists demanded, and got, equal time.
“Many people have expressed concern at FFRF’s literature, arguing that the graphic, insulting material is inappropriate in a public school setting.
“The Christians wanted to only distribute Bibles to those who wanted them—not force them on anyone, not bash other religions,” one commenter noted. “… Then the atheists got involved, and they wanted to distribute material, not to promote atheism, but to denigrate Christianity and religion in general. They are not content with presenting their belief system, they have to tear down others belief systems.””
I would love to see FFR try to stop schools from promoting islam. Seems they only want to stop Christianity.
