I'm very interested in this discussion as I have not been in the loop on the details of the concept of settler colonialism. Many on the left view it from a racial lens, which has often been true but as the article points out Japan engaged in it. And I remember that Stalin used Ukraine as a form of it -- and today's war is partially an outcome of his policies in the 30s and current eastern Ukraine is very Russian and used as a reason for the invasion. I need to do a lot more reading on the subject and there are some sources in this article.
Of course the major issue today is the question of Israel. There are lots of links in this article to check out. Of course I expect to be called a self-hating Jew for just posting it.
In the intense war of words over the Israel-Gaza war, a particular phrase has popped up repeatedly. At protests, on fliers and in some mainstream publications, it is common to see Israel described — or more likely, assailed — as a “settler-colonial” state.
The concept of settler colonialism originates in academia, where its use has surged over the past two decades, whether in case studies of particular places or sweeping master narratives that purport to explain everything since Columbus. It has also been widely taken up on the activist left, invoked in discussions of gentrification, environmental degradation, financial capitalism and other subjects.
