Trid, your truth depends on duality or binary mind set. When the Moors invaded Spain, they allowed religious freedom. Christians, Muslims, and Jews lived together in relative peace. After the Moors were driven back to Africa, the Catholic kings demanded conversion to Christianity or they were told to leave. The inquisition also demanded  doctrinal obedience with punishment as the penalty for failing. Muslim religious buidings were replaced by Catholic churches. Religious intolerance became the Truth all in the name of god.
