Do you actually believe that, say, Barack Obama [1] or Pope Leo XIV [2] are nazis? If the answer is "yes" you may have more in common with MAGA looney fringes than you think.
It is the 'democrat' looney fringe, not the MAGA looney fringe which labels everyone a nazi so I suspect that someone who labels the mentioned individuals as such is more likely to be part of the former fringe than of the latter. Had they been part of the latter the label would have been 'commie' or something along those lines.
