Who can be against progress? Don’t you want "change" so that everyone is treated well and fairly? Yes, of course.
However, progress is merely the process of moving towards a goal, not the goal itself.
The confusion is that progressivism co-opts the term "progress" to mean a singular vision: a neo-liberal techno-rationalist future of egalitarian leveling that will be beneficial for human enlightenment, comfort, and peace.
Yet, to many citizens palatable progress is a retroactive return to traditional micro-social communities, which carry the negative connotations of religious fundamentalism and Luddites.
