I couldn’t get past the 4th example of “non-violence” without laughing at how wildly revisionist they are. While each of these had non-violent components, none of them would have succeeded without violence. The housing rights act wasn’t passed until literally every city was on fire.
The British gave up their occupation of India after a decades-long nonviolent struggle by the Indian population led by Mohandas Gandhi.
The Danes, Norwegians and other peoples in Europe used civil resistance against Nazi invasion during World War II, raising the costs to Germany of its occupation of these nations, helping to strengthen the spirit and cohesion of their people, and saving the lives of thousands of Jews in Berlin to Copenhagen to Paris and elsewhere.
Labor movements around the world have consistently used tactics of civil resistance to win concessions for workers throughout the twentieth and twenty-first centuries.
African Americans used civil resistance in their struggle to dissolve segregation in the United States in the 1950s and 1960s.

I think you may be jumping to conclusions when you see something that doesn’t immediately fall into your own views. Those examples are clearly a simplified and truncated set to quickly get the point across for the purpose of an “About Us” page while there is lots of in-depth information available throughout the site.
If you have qualms with their findings or data, you’d be better off taking it up with them instead of me. I don’t purport to be an expert on this subject. I am only relaying that there is plenty of credible research, data, and analysis that shows that non-violent resistance is effective.

Here you can see how and why the book defines these. The book and its author is a major resource for the website.
