Minotaurs, if anything like their brahman brethren, can get nutrition from all kinds of roughage that us puny primates can't. So while we're scrambling around for nuts and goodberries, they can make a meal of all the weeds sprouting in terrible soil, and the odd hay bale lying around to feed someone's horses.
TL;DR: They could feasibly turn what we consider indigestible garbage-plants into calorie-rich milk.
Call it pedantry if you want, but the fascists themselves are what truly "makes fascism possible".
Yes, there are plenty of folks have culpability in allowing these fucks gain control, from short-sighted collaborators who just want profit, idiots who think "they can't really be that bad", but there's an extent to which I think we should be careful about victim-blaming well-meaning (but naive) folks who believe that Liberty and Justice will win the day (being misled by whitewashed historical narratives who erase the boots on the ground required to make social and political changes - and the organization necessary to resist the rise of fascists).
I get your point, and clearly (from the paragraph I just typed) agree to an extent - I just think it's reductive to the point of undermining the movements against fascism when "liberals" all get thrown in the same basket.
