What can we do, as a society, to eliminate extremism?

I have an English essay due about extremism and need a thesis that explains what we could all do as a society to prevent extremism and stop it from growing further.

Explanation:

   Extremism is considering extreme views or extreme measures towards, for example, politics, economics or religion. This kind of action can be dangerous because it can lead to terrorism and aggression.

The best thing that people as a society can do is promote things that will have an effect on the prevention of extremism. Society can promote these things trough the media and in that way, it can affect a great number of people. This kind of promotion is considering, for example, promoting gender quality, women's empowerment, human right, tolerance and more. People can always work in a group and plan many actions that can show people that extremism must stop.

 With good actions and teamwork, society can do anything.
