Religious dogma has historically led to conflict, violence, and human rights abuses. Dogma refers to principles that are considered absolutely true but are unable to be proven. Indoctrinating children in dogmatic religious beliefs shapes their brains in ways that make alternative views difficult to accept later in life. While religion itself may provide benefits, dogma from any system is problematic as it inhibits critical thinking and justifies treating other groups as absolutely wrong. Secularism need not oppose spirituality but argues separating religion from government authority promotes diversity and cooperation.
