The inverted red, pink, purple, black, and blue triangles have all been reclaimed by various remembrance and anti-fascist groups, particularly in Europe. For example, the Association of Persecutees of the Nazi Regime – Federation of Antifascists (VVN-BdA) and other members of the International Federation of Resistance Fighters – Association of Anti-Fascists use the red triangle as part of their emblem.
Unfortunately it initially made me think of the red triangle badges in Nazi Germany’s concentration and extermination camps.
