The Empire might seem like fascist super state, but meaningful comparisons to real historical figures are not really appropriate.
They’re 100% appropriate. Can people take them too far, and by extension essentially lose themselves in the forest of symbolism and extrapolated meaning without any storytelling context? Absolutely. It happens all the time, when people are looking to project themselves and their own experiences onto the film in numerous ways.
But even “just” Star Wars allowed for (and was intended to allow for) comparison to real historical figures.
