It seems that there is too much of a generalization here. Your given information about people calling you an alarmist is anecdotal. Where is the data that shows, from what the post is about, that all centralists act this way? I don't see how being a centralist and being anti-facist can't be true at the same time.
I fall into centralist territory, but I also believe that tyrrany comes from swinging too far to either side. Once you start moving so far in each direction you begin to have too much government overreach. Whether that comes in the form of dictating what car to drive, what is taught in school, who you can marry, or gender affirmation.
Too much control is too much control, period.
