Thank you for an excellent article that broadened my own understanding of fascism.
Let me add that at the root of the ability of fascism to take hold is excessive executive power. Much of how Trump threatened our constitutional order would be eliminated by removing the VEHICLE by which such a leader could consolidate power.
The Petition to Safeguard the Constitution [https://alcris2.medium.com/following-is-a-summary-of-6be4d81a3ddc?sk=bf21c2a6b26ea78cf6761ede5d12a96c] calls on Congress to curb the authorities it has ceded to the executive branch over centuries in targeted, critical areas so that future presidents will not have access to the kinds of powers Trump misused. It especially focuses on not allowing a president to ignore a Supreme Court decision that would allow him or her to misuse emergency power or to declare martial law.
