Yes. I am only 10 years younger than you, but a decade’s more experience is not to be discounted by any means.
I’ll push back on this and say that scholars and historians have struggled with the exact definition of fascism, but it is in my personal opinion that said scholars are MUCH closer to defining fascism today than they have even a decade ago, to the point where I actually do believe we have come to a concrete definition today.
Even your comparison of the two Wikipedia articles exemplifies this imho, although it is apparent you and I differ on our raising of the eyebrows. As the article from 2004 mainly points more to the history of fascism than the current article which, given the benefit of more data, has more data to draw from further defining fascism and how it has been expressed today.
I actually share your skepticism that this power could be wielded responsibly, which is why I’m generally not surprised nor upset at it not being a popular opinion.
In short, I am skeptical of my own beliefs, yes. And perhaps I lack your foresight, but I generally hold the belief that there aren’t other legitimate likely solutions to the eradication of fascism that exist within the current frameworks of societal public discourse, and am unwilling to relent, throw up my hands, and give up.
