Theres going to be several interpretations but for me the spirit of a fascist is simply someone who wants to control, oppress, and silence their ideology opposition. You're going to see colors of this in either party. It is usually the fringe or a systemic issue. Claiming whole parties or large swaths of people are fascists is often times going to be inaccurate.

Organizing a putsch to decapitate a branch of government and stop the certification of a fair and democratic election is pretty fascist to me.

Thats specifically why I said you're going to see colors of this in both sides. In particular the fringe left and right.
