tbh, if I ever see a nationalist blog on Tumblr, my immediate assumption (following the “politics is a mask for your personal problems” rule of thumb) is that they most likely have no sense of order in their own lives and that they have no actual heritage or history to be proud of so they externalize it all into some bullshit about traditionalist Europa or whatever just to have something to be proud of regardless of the fact that whatever they are holding onto is just a fictional version of what is just as degenerate in real life as the things they are running away from
All nations are simultaneously both fictional and real, like money.
