Trumps identity politics is reactionary in nature, itself being developed as a right wing response to the dominance of left identity politics that have been slowly creeping into mainstream culture since Obama (although you can probably trace the roots to Clinton).
Isn't everything in "cultural" politics reactionary? Civil rights to segregation. Neoliberalism to libertarianism, etc. What does something being reactionary actually tell us about the thing. In a sense, most campaigns are reactionary. They focus on FUDing the opposition more than positively promoting themselves.
IMO, reactionary is more descriptive of political climates than movements. When antagonism is a primary/defining motivator, all reactionary cliches show up. There are, obviously, movements than lean in.
