Anyone know why and where we as a people adopted the raised clenched fist? At surface review it says it stems back to 1924- adopted by communist party of Germany’s Roter FrontKampferbund ( Alliance of red front fighters ) later adopted by Nazi party.

Curious if this is just another thing we do without knowledge of true origins or if it really originated with our community and was also jacked by the culture vultures they have always been?
