If you spot any of these:

Blind faith in a leader who claims to speak for the people and calls for action with no room for doubt.

Appeals to fear or mainly disgust toward those marked as different while constructing enemies seen as both strong and weak.

Praise for tradition and rejection of modernity, glorifying life as permanent struggle in which the weak have no place.

It's probably fascism and it does get clicks, likes and votes. No need to wait for salutes, it's already fascism.
