I disagree. I think the rate of change is what's important. Just look at how much we put up in terms of voter suppression, police misconduct, increasing government surveillance and secret courts in that regard, and open discrimination of minorities and other elements of society. These are things that grew into accepted normalcy slowly, even though the ideas behind them are in my opinion insane. Currently if a police officer abuses a guy, in general as long as the guy doesn't get killed, we are ok with it as a society. That's how far we've come. We get a little irate if someone dies, but are not really angry if its just a savage beating (whilst in the 1990s there was mass rioting in the streets over savage beatings caught on tape). If you really think about it, people should be absolutely outraged by some of the things Trump and his cabinet have said and done of recent and the outrage is minimal because of acquired tolerance. I almost wonder if that's the game Trump is playing. Increasingly raise the tolerance level and push the bar as a means to buy more room for misconduct.
Fascism overnight? No. But slow changes with more consolidation of power in the hands of fewer and fewer people? Well that is already sort of happening already right? Just look at our wealth gap and what it has done to our politics with essentially a minority party having the majority control nationwide on multiple levels of government?
All of what you just argued has been historically getting better every generation.
