What I call the SJW movement is people who see the world as a battle between races, genders, sexual orientations instead of seeing every individual as a separate entity with their own virtues and weaknesses.
They often discriminate against people who belong to "privileged groups" and favor "marginalized" people in some sort of revenge for unjust things that happened in the past against these marginalized groups (and maybe for some unjust things that may still happen), and generally support positive discrimination, and even state interference in order to reach some sort of equality between these different groups of people assuming that if those things hadn't happened in the first place every group would behave the same way.
