My point is that the term "fascist" here gets used to draw attention to parallels in core ideology, and that this is unsurprising and indeed appropriate.
There will always be differences, and a narrower definition can be useful in a different discussion, but in general, I'd say recognizing the same patterns from the past is the opposite of historical illiteracy and something that we could use more of. Insisting on the finer points _in this context_ comes across as historical pedantry at best, or an inability or unwillingness to recognize the fundamental similarities otherwise.
