Conservatives believe that people need to meet the same standards, and that it is racist to not hold people to those standards. This means if a black kid at a poor school hits a teacher it's treated the same as if a white kid at a rich school hits a teacher - very seriously.
Liberals believe in intersectionalism, and that marginalized groups need unique affordances. This means accepting that if a black kid at a poor school hits a teacher, it may be because of poverty and racism and we should understand the issue in that context.
