What is the reason that people in the Middle Ages were more tolerant than people today?

 People in the Middle Ages were not necessarily more tolerant than people today. 

Tolerance and intolerance vary greatly based on time period, location, cultural and social factors, and individual beliefs. Additionally, the concept of tolerance as it is understood today did not exist in the same form in the Middle Ages.

 It is important to avoid making sweeping generalizations and to carefully consider the historical context when discussing tolerance and intolerance.
