If there is one lesson you should take to heart, it is this: the later you act, the more impossible it will become.
Right now, at this moment, society has a small window of opportunity.
People cannot get rid of autocracy by themselves, they have become controlled resources. It took millions of free people to get rid of the Nazi's.

Act how?
Bottom up.
Have conversations with your friends, the grocery store owner.

Fascism is not Hitler. It is collective, sociological behavior. Trump is a nuisance. The problem is a society engineered to give consent to the .1%, the Dark Mirror tech bro's, the christian cultists.
