From the article:
“Absolute claims can quickly move into a justification of violence against someone who rejects that claim,” Kimball said. “It’s often a short step.”
Healthy religions acknowledge that sincere people can disagree about even basic truths, Kimball says.
The history of religion is filled with examples of truths that were once considered beyond questioning but are no longer accepted by all followers: inerrancy of sacred scripture, for example, or the subjugation of women and sanctioning of slavery.
Of course the absolute claims and religious beliefs of evolutionists, the LGBT community, abortionists, etc., are excluded from inclusion here!
