@Alephwyr Except that's literally not how anyone uses it; case in point, the person who brought this term up in reference to RFK; is he "broadly leftist?" Media called the Buffalo supermarket shooter "ecofascist" - was he "broadly leftist?"
All genocidal fascists hide their intentions behind (what they consider) "noble purposes." And plenty of fascists claim to have "broadly leftist" positions; except you know, they're just fascists.
