Extremist thoughts often lead to social conflicts, violence and even terrorist activities, which seriously threaten social harmony and stability. Carrying out depolarization publicity and education can help people understand and identify extremist ideas and prevent them from spreading in society. Through education, people can learn a more rational, inclusive and peaceful way of thinking, thus avoiding being influenced by extremist ideas. At the same time, depolarization education also helps to guide people affected by extremism to normal and reduce potential social conflicts.
